Tech Tips: Vim, Facebook and Firefox’s Personas Rotator Extension
Here are three tech tips, that I felt did not necessitate their own entry.
In the Vim text editor(homepage), one can use the keybinding Ctrl+W ; O to close all windows except the current one, which will be the only one left open (hence the "O").
In Facebook (Wikipedia page) one can use Shift+Enter to start newlines in the messages you compose in the site’s composer. Press it twice to start a new paragraph.
If you are using Firefox’s Personas Rotator Extension ( Addons.mozilla.org page), then you can switch the currently shown persona ( in case you don't want it at the moment) using Ctrl+Alt+P or an alternate configurable keybinding. I discovered this latest tip by accident and can no longer imagine my life without it.
