Map Keyboard keys to mouse
-------------------------------------------------------------------
This can be useful in place where you want to use keyboard than mouse.
Packages:
sudo apt-get install xkbset
xkbset m # This will enable keyboard keys to act as mouse keys.
And then map it to keys using the command
xmodmap -e "keycode 108 = Pointer_Button3"
Here the keycode 108 corresponds to AltGr key
And the keycode can be found by using the command
xev | grep keycode
example o/p:
state 0x0, keycode 36 (keysym 0xff0d, Return), same_screen YES,
state 0x0, keycode 23 (keysym 0xff09, Tab), same_screen YES,
state 0x0, keycode 23 (keysym 0xff09, Tab), same_screen YES,
state 0x0, keycode 108 (keysym 0xfeeb, Pointer_Button3),
Pointer_Button3 is for right click
Pointer_Button2 is for middle click
Pointer_Button1 is for left click
To persist the settings across reboots.
For kde desktop, the autostart files can be placed at
~/.kde/Autostart/
Place the below lines in shell script and copy to the location above

xmodmap -e "keycode 108 = Pointer_Button3"
