Here am I looking at the different tcell.Key constants and typing different key combinations in the terminal to see the generated tcell.EventKeys in the debug log. Until I pressed Ctrl+Alt+Backspace… :-D Yep, suddenly there went my X…

So far, it appears as if I can have either only Ctrl or Alt as modifiers. But not in combination. And Shift is just never ever set at all. Interesting.

Well, in Xterm, I actually do get key combinations with the Shift modifier. Also, combinations of several modifiers just work exactly as I expect. But not in URXvt. Hmm.

@lyse@lyse.isobeef.org Unix terminals are quite limited in that regard. 🫤 You know how Ctrl works? The XOR 0x40 thing? And Alt doesn’t exist at all, it’s just a prefixed ESC byte.

I was surprised to see curses knowing about “Shift+Tab”, wondering how that is supposed to work. Well, it’s an escape sequence, of course (depending on the terminal, of course).

@movq@www.uninformativ.de Yeah, I know that terminals are super weird and messy. In both the KDE Konsole (identifying itself as TERM=xterm-256color) and xterm (TERM=xterm) it just works flawlessly. My urxvt (TERM=rxvt-unicode-256color) just doesn’t. I also tried messing with TERM in urxvt, but no luck so far.

And tcell seems to support my urxvt in general: https://github.com/gdamore/tcell/blob/v2/terminfo/r/rxvt/term.go#L144

@lyse@lyse.isobeef.org … I sure hope that they generate these files from the general terminfo database instead of maintaining their own DB. 😳

@movq@www.uninformativ.de I guess so, yes. I read something about that in some ticket. In v3 the terminfo support was dropped, though. I’m still on v2 at the moment.
