@rl_dane AltGr (right alt key) + the key left of 1 since it's a dead key it will combine so you have to press space to get it to show up by itself and not become Γ± for example, not really a problem with ~/ but it can get cumbersome, if I use the germal layout (qwertz) then it's AltGr + the rightmost key on the qwertz row the one right of ΓΌ marked with [*+~] and again it's a dead key so you have the same maybe problem that it will combine with the next chacter if you don't space it :)
