#250 Expand [event info] to show which event(s) have a keysym
Right now, there's no way to tell (short of looping over all event names) which events are bound to a keysym. To get "Select All" behaviour for Control-a, I have
event add <<SelectAll>> <Control-a> <Control-A>
in my app. What I didn't realise (as I develop on Windows) is that, on Linux, these keysyms are already added to <<LineStart>>. When someone reported that Control-a wasn't doing 'Select All', we had to guess and poke around to find what was happening. It would be helpful if
event info <Control-a>
which is currently invalid and returns an error would, instead, return a list of all events which have the keysym added.
If we have that information, it would absolutely be good to introspect it. (It would also be the sort of thing that fits with general API testability principles.)
