This seems to be a combination of -two things, neither of which I completely understand yet. Firstly, on -OS X GTK my trackpad seems to generate GDK scroll events for which -gdk_event_get_scroll_deltas returns integers rather than integer -multiples of 1/30, so we end up scrolling by very large amounts; -secondly, the window doesn't seem to receive a GTK "draw" event until -after the entire scroll gesture is complete, which means we don't get -constant visual feedback on how much we're scrolling by. - -There doesn't seem to be a resize handle on terminal windows. Then -again, they do seem to _be_ resizable; the handle just isn't shown. -Perhaps that's a feature (certainly in a scrollbarless configuration -the handle gets in the way of the bottom right character cell in the -terminal itself), but it would be nice to at least understand _why_ it -happens and perhaps include an option to put it back again. - -A slight oddity with menus that pop up directly under the mouse -pointer: mousing over the menu items doesn't highlight them initially, -but if I mouse off the menu and back on (without un-popping-it-up) -then suddenly that does work. I don't know if this is something I can -fix, though; it might very well be a quirk of the underlying GTK. - -Does OS X have a standard system of online help that I could tie into? - -Need to work out what if anything we can do with Pageant on OS X. -Perhaps it's too much bother and we should just talk to the -system-provided SSH agent?
