If you start gdb without -tui, and press ^Xo, it will switch to tui mode. I don't know if they've "fixed" this in newer versions, but I've found it useful.

That key sequence is emacs for switch to other window. If you're an emacs user but use gdb in the console it's the kind of thing you'll discover by accident sooner or later.

I am also familiar with the --tui switch for GDB and I'm wondering how this project is different. What does this project provide that gdb's tui mode does not? Can anyone that has used this expand upon why one would use cgdb over gdb's --tui mode?

With --tui there's no syntax highlighting or vim shortcuts. That's enough for me to prefer cgdb over gdb --tui. Update: I see it has scrollable gdb history, great feature!

That's enough for me to want to give it a shot! Thank you!
