level3(menu_switch)

[Andriy Gapon <avg@xxxxxxxxxxx>]

Not sure if this is a right place to ask my question but I couldn't find
any better.

I am using lv3:menu_switch to get AltGr functionality from <MENU> key,
everything works excellent, but there is one thing that I've
accidentally noticed that puzzles me a lot: this key has an auto-repeat
on it.

E.g., if I run xev and press and hold Menu key I see a fast repeating
sequence of KeyPress/KeyRelease events like the following:

KeyPress event, serial 34, synthetic NO, window 0x2e00001,
    root 0x10b, subw 0x0, time 1647313232, (-596,39), root:(504,83),
    state 0x0, keycode 117 (keysym 0xfe03, ISO_Level3_Shift),
same_screen YES,
    XLookupString gives 0 bytes:
    XmbLookupString gives 0 bytes:
    XFilterEvent returns: False

KeyRelease event, serial 34, synthetic NO, window 0x2e00001,
    root 0x10b, subw 0x0, time 1647313254, (-596,39), root:(504,83),
    state 0x80, keycode 117 (keysym 0xfe03, ISO_Level3_Shift),
same_screen YES,
    XLookupString gives 0 bytes:

KeyPress event, serial 34, synthetic NO, window 0x2e00001,
    root 0x10b, subw 0x0, time 1647313254, (-596,39), root:(504,83),
    state 0x0, keycode 117 (keysym 0xfe03, ISO_Level3_Shift),
same_screen YES,
    XLookupString gives 0 bytes:
    XmbLookupString gives 0 bytes:
    XFilterEvent returns: False

KeyRelease event, serial 34, synthetic NO, window 0x2e00001,
    root 0x10b, subw 0x0, time 1647313277, (-596,39), root:(504,83),
    state 0x80, keycode 117 (keysym 0xfe03, ISO_Level3_Shift),
same_screen YES,
    XLookupString gives 0 bytes:

xmodmap -pm produces this [truncated]:
mod5        Mode_switch (0x5d),  ISO_Level3_Shift (0x75),
ISO_Level3_Shift (0x7c)

0x75==117 of course (and you probably guessed the modifier from state
field of KeyRelease event).

I think that I've read somewhere that if a key has a real modifier
associated with it then autorepeat is automatically switched off for it.
Doesn't happen in my case. This looks very contrary to how
Shift/Control/Alt behave.

BTW, I am still using XFree86-4.5.0.
