Without trying it, I guess the browse mode might be a good idea... it
still allows for the behaviour we originally had in the proposal, but
with the added advantage of being able to browse several tooltips at
once (e.g. on a toolbar) without having to press the 'show key' then the
'hide key' for each one.

If we went ahead with that, one option might be to make the accelerator
for "hide tooltips" a second press on Ctrl+F1, rather than Esc. That
could then allow us to provide a standard CheckMenuItem (with the
accelerator Ctrl+F1) on the Help menu to toggle the display of tooltips
for focused controls (much like the menu item for turning balloon help
on/off in MacOS).

That would make the functionality more visible to the user-- at the
moment, there's no way you'd know you could summon a tooltip by pressing
Ctrl+F1, and no way of knowing how to get rid of it again.  We could
then add that menu item as a standard in the UI styleguide.

I guess it all depends on whether "browse tooltips" is something you'd
want to work desktop-wide (as Mac balloon help does) or on a
per-application basis-- anyone have any views on this?  (Personally I
always get annoyed when balloon help isn't confined to the application I
was using when I switched it on, but then again I'm using it for a
rather different reason.)
