Create keyboard shortcuts (and show available combinations in top of screen) without holding modifier keys (ctrl, super, meta, ...)
It's inspired in Doom Emacs key management and the code is based on dmenu.
Map a key to open this program (maybe \, ¡ or CapsLock key, which are never used.
Then it will show on top of the screen available key combinations. For example,
x s -> shutdowns computer
x r -> reboots computer
l w -> launch browser
l e -> launch emacs
m h -> set monitor to HDMI
m d -> dual display monitor
...
You can press Left Key to go up to the menu.
For more power, you can launch flybinds followed by some arguments key1 key2 ... to navigate to those items.
For example, let's say we have a parent item c (config) and there a child m (monitors) which have child to setup the monitors. Then, we can run flybinds c m to open flybinds directly in the monitors section.
It can be configured via the ~/.Xresources file, using the class flybinds. Check config.def.h to see what resources can be customized.
To avoid writing a script per item, you can group a script for a whole submenu. In the example of shutdown, reboot, ... we can write a simple script like this:
case "$@" in
s) poweroff ;;
r) reboot ;;
esacand only set the path of the script to the parent items.
Just play around with the program and you will understand it!
In order to build flybinds you need the Xlib header files.
Edit config.mk to match your local setup (dmenu is installed into the /usr/local namespace by default).
Afterwards enter the following command to build and install dmenukey (if necessary as root):
make clean install
