If you're on Linux (maybe macOS supports this too?) you can open the keyboard settings and turn one of several keys into the Compose/Multi key (I picked CapsLock because I rarely hit it on accident and don't use it). Then you can type all kinds of weird combinations: https://www.x.org/releases/X11R7.7/doc/libX11/i18n/compose/en_US.UTF-8.html https://www.x.org/releases/X11R7.7/doc/libX11/i18n/compose/e... For example, em dash is Compose+minus+minus+minus, en dash is Compose+minus+minus+period. It's also useful for foreign glyphs like Compose+a+a for the Nordic å, Compose+s+s for German ß (with Shift it becomes ẞ, which the new German orthography rules officially recognise!), Compose+quote+<vowel> for the various umlauts and Compose+i+period for the dotless ı (with Shift it becomes the dotted İ).
