I made a few 2-letter scripts to control the xterm keys bar, at:
http://sam.nipl.net/code/n900-x/
fs - fullscreen - hides the keys bar
tb - toolbar - shows the keys bar
kd - Tab Esc PgUp PgDn - keys default
ks - Esc < > | ^ % ~ - keys shell (I use ctrl-i for tab)
kc - | { } [ ] < > - keys C (ctrl-c in vim acts like Esc)
kb - Esc [ ] < > | % - keys brace (or python)
kv - Tab < > | dn up cr - keys virtual - (for shell with virtual kbd)
