Re: Alt+function keys and other keys
What I wonder is why even on the reference terminal xterm, some key escape sequences aren't even recognized, including simple enough ones such as ctrl-f1 or alt-f1. A possible way to fix all of this could be to allow raw character sequences to be assigned to commands in mc.keymap, such as PanelSortOrderByName = \eO5P though this would make it more difficult to use. The best solution would be to properly support all escape sequences. Date: Wed, 10 Mar 2010 22:37:04 +0100 From: Yury V. Zaytsev y...@shurup.com To: R.

Thanks, I'm glad to see someone working on this. I use GNOME terminal on Fedora and I first noticed the problem with F12, when the Ctrl-pgup and Ctrl-pgdn stopped working (it turned out developers had switched that functionality to some other key bindings that don't work on GNOME terminal). The bug reports related to that incident are here: https://bugzilla.redhat.com/show_bug.cgi?id=551062 http://www.midnight-commander.org/ticket/1938 It seems like a good idea to see which terminals are the most commonly used and focus testing on those. My guess is the GNOME terminal and KDE Konsole terminals are at the top of the list since nearly every modern distro runs one of those two desktops. Maybe there needs to be a policy that key combination changes must be tested on mainline terminals before they are accepted in released versions of MC. -Steve ___ Mc-devel mailing list http://mail.gnome.org/mailman/listinfo/mc-devel

I agree the bug is in Gnome terminal but if we know it isn't going to be fixed, then intentionally using that key combination seems like an intentional choice to drop support for a high profile terminal. To me, it makes more sense to map the key combinations that work in the majority of widely used terminals and then select among those the ones to be used in MC. In other words, why not try to make MC work with the maximum number of terminals instead of intentionally breaking compatibility with some of them? The key combos can be remapped by the end user, so it should be possible to offer an MC that works out of the box for nearly everybody. Then, if a particular user really wants to use a key mapping that works only in his terminal and no others, he can manually change it without breaking things for everyone else. -Steve ___ Mc-devel mailing list http://mail.gnome.org/mailman/listinfo/mc-devel
