What do you propose to be used as keyboard shortcuts for arrows
in SDL GUI?

Pressing </> to switch Joystick interface in Joystick dialog
and shortcut for given joy option, is 10x nicer to use to change
what port has joystick, than moving focus to arrow, then to joy
option, back to arrow, back to joy option...  Especially when
focus changing doesn't have key repeat.

(Personally I prefer using shortcuts also over mouse.)

I'm not yet giving up either of them.  Most important of the buttons
for keyboard navigation is '..', without that Fsel cannot be used
just with keyboard.  Rest I could consider.

Letter shortcuts in the list would make it much more convenient to
use with keyboard, when you know the name of the file you want.
Just press the first letter and scroll down few items if needed,
to select the desired file, then accept the dialog.  I guess it
should also focus the first filename.

Do you have other proposals how the Fsel list could be made easier
to navigate with keyboard?


Btw. I added your UTF-8 -> latin1 conversion for SDL GUI (filename)
strings with same ifdefs as what were used in Max' GEMDOS HD patch.
