I just added two new shortcuts on the following webpage: https://wiki.geany.org/howtos/sorted_keyboard_shortcuts
In the table with the title "Editing" I wrote this text to make the list complete: ``` |Alt Gr-character|Insert one special character|Press on the keyboard at the same time the Alt Gr key and one symbol key, like a number or a letter.| |Alt Gr-Shift-character|Insert one special character|Press on the keyboard at the same time the Alt Gr key, the Shift key and one symbol key, like a number or a letter.| ```
