Standard Shortcuts

Kernel

These are low level shortcuts that are considered to be used for debugging. Whenever possible, it is recommended to use these instead of doing a hard shutdown (holding power button to shutdown the motherboard).

Must be activated first with echo "1" > /proc/sys/kernel/sysrq or if you wish to have it enabled during boot, edit /etc/sysctl.conf and set kernel.sysrq = 1

A common idiom to remember this is "Reboot Even If System Utterly Broken" (also referred to as "REISUB").

Copy selected text to clipboard, or paste from clipboard

xkeyboard-config disable keyboard mouse by default after the version 2.0.1.To enable it, changing the following line in /usr/share/X11/xkb/symbols/pc:

key <NMLK> { [ Num_Lock ] }; 

back to as it was in version 2.0.1:

key <NMLK> { [ Num_Lock, Pointer_EnableKeys ] };

User Customization

Readline

This example adds keys that allow (in vi-mode) to search backward through the history for the string of characters between the start of the current line and the point. This is a non-incremental search.

.inputrc
set editing-mode vi
set keymap vi-insert
"\C-r": history-search-backward
"\C-e": history-search-forward

X11

Modifying the Keyboard Layout

This example changes the CapsLock key to only activate caps lock when the Shift key is also pressed

.xinitrc
xmodmap -e 'keycode  66 = NoSymbol Caps_Lock Caps_Lock'

The keycode of the CapsLock key can be found in the output of xmodmap -pk

Key Binding for X-Selection-Paste

Users who prefer to work rather with the keyboard than the mouse may benefit from a key binding to the paste operation of the middle mouse button. This is especially useful in a keyboard-centered environment. A workflow example is:

  1. In Firefox, select a string you want to google for (with the mouse).
  2. Hit <Ctl>K to enter the "google search" field.
  3. Hit F12 to paste the buffer, instead of moving the mouse pointer to the field and center-click to paste.

The method suggested here uses three packages available in the official repositories:

  • xsel to give access to the x-selection-buffer content.
  • xbindkeys to bind a key-stroke to an action.
  • xvkbd to pass the buffer string to the application by emulating keyboard input.

This example binds the x-selection-paste operation to the <F12> key:

.xbindkeysrc
"xvkbd -no-jump-pointer -xsendevent -text "\D1`xsel`" 2>/dev/null"
    F12

The "\D1" code prefixes a 100ms pause to inserting the selection buffer (see the xvkbd home page).

Note: Depending on your X configuration, you may need to drop the -xsendevent argument to xvkbd.

The keycodes for keys other than <F12> can be determined using xbindkeys -k.

Firefox

Use the customizable-shortcuts add-on.
