gdb: graphic (tui) mode

A little known fact about gdb is that you can use it in graphics mode, called TUI. Yes, you can obviously use DDD or a similar front end but that's not even nearly as cool as using a console based GUI (!), is it?

The easiest way is to start gdb like this:

gdb -tui

That will display the usual gdb console plus a code listing, similar to the code listing you get using the "list" command but shown in another window. Alternatively you can press C-X C-A (both, in that order) while in gdb to switch between TUI mode and back.
