[MACTCL] Problems with modifiers

[Trevor W. <pha...@gm...>]

I am using 8.5.15 (though I have seen this same issue with 8.5.17).  When I enter a modifier key such as Shift, Control, Alt or Command, and attempt to get the keys value using the bind %K value, instead of receiving a value like “Shift_L” and the like, I instead get the value “??”.

I was able to reproduce this issue with a script provided on the wiki.tcl.tk page.  I have attached that script to this e-mail.

I appreciate any help tracking this issue down.

Thanks,
Trevor Williams

Running your script, here is one example output I see for Shift A:

Unmodified <KeyRelease> with <%K> equal to <A> and <%A> equal to <A>
Unmodified <KeyRelease> with <%K> equal to <??> and <%A> equal to <{}>

This doesn't seem entirely consistent with what you are reporting: note 
that the A is captured there.

Regardless, this is an area I am unfamiliar with, including the use case 
for getting the key pressed with a modifier. If you want to investigate 
submitting a patch, the relevant code seems to be in tkMacOSXKeyboard.c.

I think that if you just hit the Shift key, you will get a KeyPress event where the keysym value is ??.  I'll try to investigate some more.  At least it sounds like the problem is not isolated to just me.
