metaSendsEscape

Occasionally we can found that the Bash key-binding such as M-f/M-b will not work in XTerm (this happened both in my laptop and desktop), to solve this problem, just press `Control' and left mouse and check the item `Meta Sends Escape' from the main options.

To turn it on permanently, add the following line to configure file '/etc/X11/app-defaults/XTerm':

*metaSendsEscape: true
