It looks like we've hardcoded the values such that we assume get_key() returns 265 for F1 and 266 for F2 and 258 for the down key.

However, we also take into account that F1 can be returned as a series of key presses (the escape sequence), {27, 91, 49, 49}. F2 is assumed to be {27, 91, 49, 50} and the down key is {27, 91, 66}.

None of these values are universal. Fixing this requires hooking into terminfo or termcap to determine what these keypresses really are. However, it is forseeable that termcap or terminfo might report back that there is no F1 or F2 key for this terminal (e.g. if TERM and TERMCAP are set incorrectly, or if someone's ssh'd multiple times and the TERM info got lost in the chain or - much more rarely - the person is using a keyboard with no F1 key).

I propose that we take some universal keys that are not used for anything by the trace screen right now, and use them as seconds that have the same function.

E.g. '1' can be F1, '2' can be F2, and 'j' can be the down key.
