My Macbook laptop keyboard doesn't have a SysReq key. Can I change an existing key to act like SysReq?

    This is an easy task once you know how to do it.

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

      xev

    2. It will open a blank window, click on your key and then check the terminal output,

    3. For example, when I press k the terminal shows me:

      KeyRelease event, serial 34, synthetic NO, window 0x2600001,    
    root 0x286, subw 0x0, time 1577277172, (-63,525), root: (902,565),    
    state 0x10, keycode 45 (keysym 0x6b, k), same_screen YES,    
    XLookupString gives 1 bytes: (6b) "k"    
    XFilterEvent returns: False

      From which I know the keycode for my k key is 45.

    4. Change them as you like creating this file:

      gedit ~/.Xmodmap

      Its contents should look like this example:

      keycode  45 = Print Sys_Req Print Sys_Req

    5. Then run (or reboot):

      xmodmap ~/.Xmodmap
