On my Ubuntu 11.10 machines running byobu 4.37 I can use the key combination ctrl-left / ctrl-right to jump a word at a time in the terminal. However, on my Ubuntu 12.04 machines with byobu 5.17, this no longer works.
I've read that byobu has remapped those key combinations to resize splits, and now alt-left and alt-right have the desired effect. However, I'm unable to find where alt-left and alt-right are mapped, in order to remap ctrl-left and ctrl-right. If I unmap the keybindings for ctrl-left and ctrl-right, then the cursor moves only 1 character at a time, not 1 word at a time.
