bindkey's using "Alt" are not working

This works for me. Sometimes I've seen this fail because something in your windowing system is intercepting the keys before the application is seeing them.

BTW, Alt modifiers are used for other purposes by default in IC61 (for menu accelerators - although this can be turned off).

There's some debug settings that can be done to track events - but these use private functions so I'd prefer not to effectively document them in a public forum - so please log a service request with customer support and somebody should be able to help you (you can always reference this forum thread in the SR and ask the AE to contact me if they want some pointers).

You could always run "xev" in a terminal window and then hit the Alt key when your cursor is over the window (note that moving the cursor will print out a ton of event information). It should show something like this when you press and release the Alt key:

 KeyRelease event, serial 34, synthetic NO, window 0x5a00001,
    root 0x27d, subw 0x0, time 12934570, (96,96), root:(1787,121),
    state 0x8, keycode 64 (keysym 0xffe9, Alt_L), same_screen YES,
    XLookupString gives 0 bytes:
    XFilterEvent returns: False

KeyPress event, serial 34, synthetic NO, window 0x5a00001,
    root 0x27d, subw 0x0, time 12942394, (96,96), root:(1787,121),
    state 0x0, keycode 64 (keysym 0xffe9, Alt_L), same_screen YES,
    XLookupString gives 0 bytes:
    XmbLookupString gives 0 bytes:
    XFilterEvent returns: False
