Ever since upgrading from Xubuntu 20.04 to Xubuntu 22.04.1, I've been having a problem with certain key bindings for some keypad keys. These are properly defined in my .muttrc file and used to work under the previous version of the OS, but now report "Key is not bound," even though when I type "?", the bindings are all properly listed.
I was running mutt 2.1.4 which was the latest version in the repository. I downloaded the just released 2.2.8, compiled and installed it, but it made no difference. I'm using a Sun Type-6 keyboard with the full keypad on the right. The majority of the keys work, while others do not. For example, in .muttrc I have the following: bind generic <esc>[25~ previous-entry # Keypad 0 Key bind generic <esc>[26~ previous-entry # Keypad 1 Key bind generic <esc>[28~ last-entry # Keypad 2 Key bind generic <esc>[31~ next-entry # Keypad 3 Key bind generic <esc>[33~ previous-entry # Keypad 4 Key bind generic <esc>[42~ select-entry # Keypad 5 Key bind generic <esc>[43~ next-entry # Keypad 6 Key bind generic <esc>[44~ previous-page # Keypad 7 Key bind generic <esc>[45~ first-entry # Keypad 8 Key bind generic <esc>[46~ next-page # Keypad 9 Key bind generic <esc>OI first-entry # Keypad Num_Lock Key bind generic <esc>Oo first-entry # Keypad / Key bind generic <esc>Oj last-entry # Keypad * Key bind generic <esc>Om select-entry # Keypad - Key bind generic <esc>Ok next-entry # Keypad + Key bind generic <esc>[32~ next-entry # Keypad . Key bind generic <esc>OM next-entry # Keypad Enter Key Keys 0-9, period and Num_Lock work, but Keys /*-+ and Enter do not, despite having the accurate escape sequences here and showing up properly defined on the help page. Notice that the Num_Lock key has <esc> followed by two letters and that works, but the others with the same format fail. I realized that my keys emit different codes if, for example, Alt is pressed, so I added the following entries as a test. bind generic <esc>O3o first-entry # Keypad / Key bind generic <esc>O3j last-entry # Keypad * Key bind generic <esc>O3m select-entry # Keypad - Key bind generic <esc>O3k next-entry # Keypad + Key bind generic <esc>O3M next-entry # Keypad Enter Key Now, using Alt, the /*+ and Enter Keys work but the minus (-) key still fails. I tried using the what_key function, but it's of little use as it only reports the last character of the escape sequences. I've had a long running discussion over on comp.mail.mutt with no results so far, so I wanted to ask here and see if anyone has a clue as to what might be wrong. And BTW, I use custom mappings of all the keypad keys when editing using vim, and another set of mappings for the less pager and everything works perfectly in these cases, so the problem seems to be specific to mutt. Thanks for any insights. Regards, -- Jeffery Small
