I'm trying to find a Linux system-wide method of inputting a non-breaking space ("hard space") that does not rely on an application-specific keyboard shortcut.
In Windows, you can do this by holding down the Alt key and typing "0160" using the keypad. I find that one Linux equivalent of this is doing Ctrl-Shift-U then typing the hexcode "00A0".
Does anyone know of an easier - or at least easier-to-remember - method than this?! I have tried various alt/alt-gr combinations, to no avail.
