Typing L with stroke with us-intl-altgr

  • 772

How do I type an L with stroke or ł, which appears notably in Polish, when using the us-intl-altgr keyboard mapping for X? More generally, is there a way to find out systematically how I can produce a certain symbol with a given keymap?

I have searched online and found several illustrations of this layout, but none seems to include this symbol.

  1. A generic method to type a character, which is not present with the keyboard layout you are using, is to type it using its code points.

    So for the example you mentioned:

    Ctrl+Shift+U followed by 0142 followed by Enter => ł

    Answering my own question after some research.

    A list of defined keys is in /usr/share/X11/xkb/symbols/us. The character ł appears there as lstroke, and it is unfortunately not defined in the altgr-intl section, unfortunately (but only in colemak).

    A different way to obtain it would be with the dead key dead_stroke followed by l. Unfortunately, the key dead_stroke isn't defined in altgr-intl either (but only in mac). So the answer is that there is no way to enter that symbol with the "vanilla" altgr-intl apart from the cumbersome method described in @GunnarHjalmarsson's answer, which allows to enter a generic Unicode codepoint: Ctrl+Shift+U, 0142, Enter.

    There is a different solution, though: defining a Compose key. Using gnome-tweaks, one can set up a modifier key (for instance, right-alt, or caps lock) to act as a compose key. Then, pressing compose, /, l produces ł.
