yes (kterm has tsl, because it actually implements a status line). > > You may consider this (from screen): > > > > XT (bool) Terminal understands special xterm sequences (OSC, > > mouse > > tracking). > > You're suggesting using this as an indicator of whether to use de facto, > compiled-in escapes for status/title strings? I find this capability > defined only in the following terminfos from ncurses-5.7: actually it's in several - other than xterm and rxvt - since I'd added it in 2010 to help out with "screen". There's no reason why it couldn't be added to xterm and rxvt (other than that it was unnecessary for the purpose at that time). -- Thomas E.
