I’m new to Ubuntu and in Windows I used to have AutoHotkey constantly running so I could input letters with tildes (á, é, ñ, etc.) with certain commands Ctrl+Alt+letter. Apparently AutoHotkey is not available for Ubuntu so I tried using AutoKey but it kept freezing and it mostly didn’t work. Now I tried making custom desktop shortcuts with the keyboard configurations but they don’t work and I don’t know why. When I press the keys the word is not written. Does anyone have any suggestion?
EDIT: I added the pictures so you can see the shortcuts. Whenever I press those keys the cursor blinks as if a letter is being written but no actual letter is.
