Use Apple keyboard command key in Fedora-like system with MWM

Question

I want to be able to CMD-TAB between windows using an Apple keyboard on a Fedora-like system using MWM.

• The OS is an in-house distro, not a standard Fedora distribution.
• Pressing ALT-TAB currently switches to the next window

• I have re-mapped the left CMD key to ALT:

  • xev shows that the CMD key is keycode 115

  • my ~/.Xmodmap file has the following line:

    keycode 115 = Alt_L

  • When I run xev and press the left CMD key, I get the following output:

    KeyPress event, serial 24, synthetic NO, window 0xc00001, root 0x1b6, subw 0x0, time 614726707, (698, 1524), root: (721, 1547), state 0x0, keycode 115 (keysym 0xffe9, Alt_L), same_screen YES, XKeysymToKeycode returns keycode: 64 XLookupString gives 0 bytes: XmbLookupString gives 0 bytes: XFilterEvent returns: False

But when I press CMD-TAB nothing happens. What am I missing?
