I understand this is likely an effort that will never be entirely perfect and I expect the function to grow a bit more to cover a few more corner cases. since the tests are fairly well defined I don't expect speed issues for the most part. > Thanks for the work Nate.

In some cases a different value needs to be used (see the Xterm section) to assign the value into the range known by keyname() and define_key() as listed in the names.txt file. > If I remember correctly by doing so I was able to map nearly all used > key combinations in tlf to the new ncurses keys.

The Gnome Terminal I installed had a handy configuration selection to disable all shortcuts which enabled nearly all the keys. Alt-Space was still caught by Xfce for the window menu. I also found that Xfce Terminal gives the same key code for Alt-A as with Alt-Shift-A while Gnome Terminal and Xterm gave separate codes for each. > I had hoped that with ncurses doing the key decoding that we could drop > the different handling for different terminal emulations. But that > seems to be not so. The good thing is that we can limit the custom coding to just a few corner cases which is a good thing. I'm surprised that the current batch of corner cases is already this large, but results from Ervin and Pierre have been encouraging. > Let me add two more terminal settings which we should check - that is > plain linux console and screen and/or tmux. I did a quick check on plain Linux Console on my T410 laptop but need to do so with a 101 key keyboard. I do use tmux (right now to access Mutt remotely) so it is also an easy test. In fact I did some tests this morning from a computer running Windows 7 and Putty and found that setting the keyboard entry to use Xterm gave me the F1-F4 keys. I'd been scratching my head over that for a long time which was a headache for using Midnight Commander remotely. Nice to know this exercise helped me fix that. > Maybe it is time to sort it out and get a solid solution. Nate it would > be nice if you could lead that work.

I'll probably get a bit more done over the next couple of weeks and get a branch pushed out for wider testing. 73, Nate -- "The optimist proclaims that we live in the best of all possible worlds.
