I have an app with a notebook.
In some tabs I may need the same bindings, for example I might want <Alt-

to click a Save button in one tab but to click a [X] Show tooltips

Checkbutton in a different tab. So clearly I can't do:
bind . <Alt-s> ...
since I need it to work per tab.

In one tiny app eg this works fine, but in a more substantial one it
doesn't work at all.

Both are shown below.
