Dear people who know all these things.
I have a US keyboard on my laptop with UK (or possibly Irish) mapping. As a result nothing I do will give me the pipe symbol | without copy paste. Can I create some kind of shortcut keystroke to get it? HALP!

@Antiqueight If you're on Windows and don't mind installing a program, I think a lot of people use AutoHotKey for mapping key combos or abbreviations to send hard- or impossible-to-type things.

(the following autohotkey script should map Control-backslash to the pipe symbol, for instance.)

AutoHotkey

Free keyboard macro program. Supports hotkeys for keyboard, mouse, and joystick. Can expand abbreviations as you type them (AutoText).

@JoshGrams Ah, I can on this computer so I will try that - thank you. That's probably the kind of thing I need.
