Yes, Alt-s does not work. If I change it to Mod1, that triggers but
still adds "s" to the entry widget.

I haven't had that opportunity, however I was debugging whether it was
an xmodmap issue.

My xmodmap output:
----------------------------------------------------------------------
$ xmodmap
xmodmap:  up to 5 keys per modifier, (keycodes in parentheses):

shift       Shift_L (0x32),  Shift_R (0x3e)
lock
control     Control_L (0x25),  Control_L (0x42),  Control_R (0x69)
mod1        Alt_L (0x40),  Meta_L (0xcd)
mod2        Num_Lock (0x4d)
mod3
mod4        Alt_R (0x6c),  Super_L (0x85),  Super_R (0x86),  Super_L (0xce),  Hyper_L (0xcf)
mod5        ISO_Level3_Shift (0x5c),  Mode_switch (0xcb)
----------------------------------------------------------------------

This is really plain. The only change is Alt_R is bound to mod4. I'm
using the left Alt in my testing. At this point, I'm pretty sure its
not xmodmap.

Every other GUI app works fine with Alt. Emacs, Firefox, Pidgeon,
Dolphin, Urxvt, and the list goes on. If there had been a problem
anywhere else with Alt, I'd have immediately tracked it down as a
local configuration issue.

Ubuntu's TCL 8.5.8-2build1 and Tk 8.5.8-1.

No other, but I may be upgrading to the latest Ubuntu shortly.

Thanks.
