 ### Issues and solutions
 
+#### Enable AltGr
+
+The keyboard has a keypad enter instead of an AltGr. The first key on
+the right side of the spacebar is the Apple "command" key. On its
+right is the keypad enter. We can make it act as an AltGr.
+
+If your operating system is Trisquel or other dpkg-based distribution,
+there is an easy solution. Under root (or sudo) run
+
+      # dpkg-reconfigure keyboard-configuration
+
+and select the option "apple laptop", leave other settings as their
+defaults until you are given the option "Use Keypad Enter as
+AltGr". Select this. The keypad enter key will then act as an AltGr
+everywhere.
+
+For Parabola or other systemd-based distributions you can enable AltGr
+manually. Simply add the line
+
+      KEYMAP_TOGGLE=lv3:enter_switch
+
+to the file /etc/vconsole.conf and then restart the computer.
