Make shortcut for navigational functions

Question

Is there anyway to create shortcuts for functions like Home, End, Pg Up, Pg Down, etc? I frequently use the aforementioned keys, however those keys are only available when the numpad is disabled - there is no dedicated keys for those function on my laptop. I was thinking of using the Fn key to trigger them even when the numpad is enabled.

Answer 1

Approach 1. Using Fn key

1. Check the keycode of yours key. Run this program at terminal.

   xev
   

   

   At this example, the terminal shows that the keycode for my k is "45".

2. Change them as you like creating this file:

   gedit ~/.Xmodmap
   

   It's contents should look like this example:

   keycode 180 = Home End Down
   

   (keycode 180 is for Fn+F3 at my notebook)

   Ilustration:

   

   (Obs.: if I want to change my k I must use keycode 45 as showed at step "1", if I want to change my Fn+F3 I must use keycode 180).

3. Log out and log back in or reboot or run this:

   xmodmap ~/.Xmodmap
   

Approach 2. Using a shortcut (combination keys)

1. Install xdotool

   sudo aptitude install xdotool  
   

2. Open Gnome Keybindings

   gnome-keybinding-properties  
   

3. Create the shortcut with this commands:

   xdotool getactivewindow key Home
   xdotool getactivewindow key End
   xdotool getactivewindow key Page_Up
   xdotool getactivewindow key Page_Down
   

   Example:

   

Enjoy!
