The default terminal emulator provided in Maemo Leste is osso-xterm.
Modifying soft keys
Through gconf, it is possible to modify the soft keys that show up on the bottom bar of osso-xterm.
For example, to have a series like "Tab, Escape, Arrow Down, Arrow Up" we would issue two gconftool commands, one which would modify the labels, and the other which would actually map it to the keys.
$ gconftool-2 --set -t list --list-type string /apps/osso/xterm/key_labels "[Tab,Escape,Dn,Up]"
$ gconftool-2 --set -t list --list-type string /apps/osso/xterm/keys "[Tab,Escape,Down,Up]"
