Navigating Links and Elements:
f Starts hint mode, highlighting all the clickable elements in the current view and
gives them, on default settings, numeric labels.
Elements and links can now be clicked by either typing the respective number
or part of their textual name/description, narrowing the selection down, or, in
case there is only one element that matches it, clicking it.
After the element has been clicked, hint mode ends.

Hint mode special keys are:
Enter/Return/<CR> Selects the first highlighted or tab selected hint.
Tab Moves focus to the next hintable item.
<LeaderKey> Default mapping is \, temporarily treats numeric input
as text input instead of hint selection input.
Escape Exits hint mode without selecting anything.

F Same as f, but items are shift left clicked instead of simply left clicked.

;{Mode} Starts extended hints mode, working just like f but with specified effects see below.

;; Focuses an element without clicking it.
;s Saves the destination of the link.
;f Focuses a frame.
;o Opens the location in the current tab.
;t Opens the location in a new tab.
;b Opens the location in a background tab.
;w Opens the location in a new window.
;O Generates an open prompt with the location as the URL, similar to the O key.
;T Generates a tabopen prompt with the location as the URL, similar to the T key.
;W Generates a windowopen prompt with the location as the URL, similar to the W key.
;y Copies the location.
;Y Copies the locations text description.

g;{Mode} Starts extended hints mode and stays there until Escape is pressed.
After a hint has been selected any previously narrowed down selection will be
reset to allow the selection of different items.

gi Focus last used input field. If there was no last used input field it will
Use the first available one. Good for search engines.

Using QuickMarks:
M{a-zA-Z0-9} Binds the current URL to the key specified. Example: Ma binds the current URL to a.
go{a-zA-Z0-9} Jumps to the QuickMark bound to the key specified.
gn{a-zA-Z0-9} Jumps to the QuickMark bound to the key specified in a new tab.

spectr wm keyboard reference
Layouts are handled dynamically and can be changed on the fly. There are three standard layouts (stacking algorithms): vertical, horizontal and maximized (indicated in the status bar as [|], [-] and [ ])

There is the concept of a master area (a working area). Any window can be switched to become the master and will then be shown in the master area. The master area is the left (top) portion of the screen in vertical (horizontal) mode. The size of the master area can be adjusted with the keys. By default the master area holds one window, but this can be increased.

The area excluding the master area is called the stacking area. New windows are added to the stacking area. By default the stacking area has one column (row) in vertical (horizontal) mode, but his can be increased.

Windows may be moved to a floating layer -- i.e. removed from the tiling management. This is useful for programs which are not suitable for tiling.

Some of the most useful key bindings:


Meta+Shift+Return: open terminal
Meta+p: dmenu (then type the start of the program name and return)
Meta+1/2/3/4/5/6/7/8/9/0: select workspaces 1-10
Meta+Shift+1/2/3/4/5/6/7/8/9/0: move window to workspace 1-10
Meta+Right/Left: select next/previous workspace
Meta+Shift+Right/Left: select next/previous screen
Meta+Spacebar: cycle through layouts (vertical, horizontal, maximized)
Meta+j/k: cycle through windows forwards/backwards
Meta+Tab/Meta+Shft+Tab: same as Meta+j/k
Meta+Return: move current window to master area
Meta+h/l: increase/decrease size of master area

Advanced stacking

Meta+,/. : increase/decrease the number of windows in master area (default is 1)
Meta+Shift+,/. : increase/decrease number of columns(rows) in stacking area in vertical(horizontal) mode (default is 1)
Meta+Shift+j/k: swap window position with next/previous window
Meta+t: float<->tile toggle

Mouse bindings

Mouseover: focus window
Meta+LeftClick+Drag: move window (and float it if tiled)
Meta+RightClick+Drag: resize floating window
Meta+Shift+RightClick+Drag: resize floating window keeping it centred

Other useful bindings

Meta+x: close window
Meta+Shift+x: kill window
Meta+b: hide/show status bar
Meta+q: restart spectrwm (reset desktops and reread spectrwm config without stopping running programs)
Meta+Shift+q: exit spectrwm



spectrwm provides many functions (or actions) accessed via key or mouse

The current mouse bindings are described below:

M1 Focus window
M-M1 Move window
M-M3 Resize window
M-S-M3 Resize window while maintaining it centered

Google Search Operators - Google Guide

If you start your query with allinanchor:, Google restricts results to pages containing all query terms you specify in the anchor text on links to the page. For example, [ allinanchor: best museums sydney ] will return only pages in which the anchor text on links to the pages contain the words “best,” “museums,” and “sydney.”


If you start your query with allintext:, Google restricts results to those containing all the query terms you specify in the text of the page. For example, [ allintext: travel packing list ] will return only pages in which the words “travel,” “packing,” and “list” appear in the text of the page.


If you start your query with allintitle:, Google restricts results to those containing all the query terms you specify in the title. For example, [ allintitle: detect plagiarism ] will return only documents that contain the words “detect” and “plagiarism” in the title.


If you start your query with allinurl:, Google restricts results to those containing all the query terms you specify in the URL. For example, [ allinurl: google faq ] will return only documents that contain the words “google” and “faq” in the URL, such as “”.


If you include author: in your query, Google will restrict your Google Groups results to include newsgroup articles by the author you specify. The author can be a full or partial name or email address.

The query cache:url will display Google’s cached version of a web page, instead of the current version of the page.

If you start your query with define:, Google shows definitions from pages on the web for the term that follows.

This is an undocumented alias for filetype:.

If you include filetype:suffix in your query, Google will restrict the results to pages whose names end in suffix.

If you include group: in your query, Google will restrict your Google Groups results to newsgroup articles from certain groups or subareas. For example, [ sleep ]

This is an undocumented alias for info:.

If you include inanchor: in your query, Google will restrict the results to pages containing the query terms you specify in the anchor text or links to the page. For example, [ restaurants inanchor:gourmet ] will return pages in which the anchor text on links to the pages contain the word “gourmet” and the page contains the word “restaurants.”

The query info:URL will present some information about the corresponding web page. For instance, [ ] will show information about the national hotel directory home page.

Note: There must be no space between the info: and the web page URL.

If you include insubject: in your query, Google will restrict articles in Google Groups to those that contain the terms you specify in the subject. For example, [ insubject:”falling asleep” ] will return Google Group articles that contain the phrase “falling asleep” in the subject.

The query intext:term restricts results to documents containing term in the text. For instance, [ Hamish Reid intext:pandemonia ] will return documents that mention the word “pandemonia” in the text, and mention the names “Hamish” and “Reid” anywhere in the document (text or not).

Note: There must be no space between the intext: and the following word.

The query intitle:term restricts results to documents containing term in the title. For instance, [ flu shot intitle:help ] will return documents that mention the word “help” in their titles, and mention the words “flu” and “shot” anywhere in the document (title or not).

Note: There must be no space between the intitle: and the following word.

If you include inurl: in your query, Google will restrict the results to documents containing that word in the URL. For instance, [ inurl:print ] searches for pages on Google Guide in which the URL contains the word “print.” It finds pdf files that are in the directory or folder named “print” on the Google Guide website. The query [ inurl:healthy eating ] will return documents that mention the words “healthy” in their URL, and mention the word “eating” anywhere in the document.

Note: There must be no space between the inurl: and the following word.

The query link:URL shows pages that point to that URL. For example, to find pages that point to Google Guide’s home page, enter:

[ ]

If you include location: in your query on Google News, only articles from the location you specify will be returned. For example, [ queen location:canada ] will show articles that match the term “queen” from sites in Canada. Many other country names work; try them and see.

If you include movie: in your query, Google will find movie-related information.

The query related:URL will list web pages that are similar to the web page you specify. For instance, [ ] will list web pages that are similar to the Consumer Reports home page.

Note: Don’t include a space between the related: and the web page url.

If you include site: in your query, Google will restrict your search results to the site or domain you specify. For example, [ admissions ] will show admissions information from London School of Economics’ site and [ peace site:gov ] will find pages about peace within the .gov domain. You can specify a domain with or without a period, e.g., either as .gov or gov.

Note: Do not include a space between the “site:” and the domain.

If you include source: in your query, Google News will restrict your search to articles from the news source with the ID you specify. For example, [ election source:new_york_times ] will return articles with the word “election” that appear in the New York Times.

If you enter a query with the word weather and a city or location name, if Google recognizes the location, the forecast will appear at the top of the results page. Otherwise, your results will usually include links to sites with the weather conditions and forecast for that location.
