Lets assign hot key to switch between source/visual and source, that
will be faster then using mouse. The same about Link/Unlink - hot key
would be fine for that.
Switch between pages is Ctrl+PgUp/PgDown, and we should actually switch the Visual/Source
pages - it would make it more logical too imo.
I'm not sure if we can find any good shortcut for link/unlink since almost every key
is already taken.
But let's get the button first, assigning a shortcut we can do down the road..
