Pyperclip is a clipboard module for Python, handling copy/pasting from the X11 clipboard

This utility for X.org uses a modifier key as another key when pressed and released on its own. The default behaviour is to generate the Escape key when Left Control is pressed and released on its own.

xsecurelock is an X11 screen locker which uses a modular design to avoid the usual pitfalls of screen locking utility design.

As a consequence of this design, you shouldn't use the usual screen locker service with xsecurelock. Instead, add a helper binary to your operating-system's privileged-programs field:

(privileged-programs
 (cons*
  (privileged-program
   (program (file-append xsecurelock "/libexec/xsecurelock/authproto_pam"))
   (setuid? #t))
  %default-privileged-programs))

wlrctl is a command line utility for miscellaneous wlroots Wayland extensions. At this time, wlrctl supports the foreign-toplevel-mangement (window/toplevel command), virtual-keyboard (keyboard command), and virtual-pointer (pointer command) protocols.

Rxvt-unicode (urxvt) is a colour vt102 terminal emulator intended as an xterm replacement for users who do not require features such as Tektronix 4014 emulation and toolkit-style configurability.

autocutsel tracks changes in the server's cutbuffer and clipboard selection. When the clipboard is changed, it updates the cutbuffer. When the cutbuffer is changed, it owns the clipboard selection. The cutbuffer and clipboard selection are always synchronized.

Wayout takes text from standard input and outputs it to a desktop-widget on Wayland desktops.

Xautolock monitors input devices under the X Window System, and launches a program of your choice if there is no activity after a user-configurable period of time.

xtrlock locks the X server till the user enters their password at the keyboard. While xtrlock is running, the mouse and keyboard are grabbed and the mouse cursor becomes a padlock. Output displayed by X programs, and windows put up by new X clients, continue to be visible, and any new output is displayed normally. The mouse and keyboard are returned when the user types their password, followed by Enter or Newline. If an incorrect password is entered the bell is sounded. Pressing Backspace or Delete erases one character of a password partially typed; pressing Escape or Clear clears anything that has been entered.

fuzzel is a Wayland-native application launcher, similar to rofi's drun mode. It has Emacs key bindings and remembers frequently launched applications. The font and colors can be configured.

bemenu is a dynamic menu which allows the user to flexibly select from a list of options (usually programs to launch). It renders the menu graphically with X11 or Wayland, or in a text terminal with ncurses.

clipnotify is a simple program that, using the XFIXES extension to X11, waits until a new selection is available and then exits.

It was primarily designed for clipmenu, to avoid polling for new selections.

clipnotify doesn't try to print anything about the contents of the selection, it just exits when it changes. This is intentional -- X11's selection API is verging on the insane, and there are plenty of others who have already lost their sanity to bring us xclip/xsel/etc. Use one of those tools to complement clipnotify.
