I know we can insert some unicode characters by pressing ALT+[code] combination under Windows, right? I would like to have a similar option under Ubuntu, however in addition to that I'd need to choose my shortcut keys and text to be inserted. For example, I want to insert "⭐" character with a combination (it doesn't matter what combination, it may be even ALT + SHIFT + CTRL + 123).
Is this even possible?
