Steps:
Just as I posted this, it is working in game now. But if there is a particular fix to this I would like to know about it as well. Thank you!
- My Alt+1~= keys are set to Hotbar 3.
- When the run for Xelphatol dungeon started, I tried to press my keys on Alt 2~4 but nothing happened.
- Throughout the dungeon run I tried the other numbers with the Alt key as well but it seems that only Alt+1 worked.
- After I was done, I realized that Alt+0, Alt+-, and Alt+= worked too. The only ones that aren't working were Alt+2~9.
- Also, when I cleared the keybinds I can't seem to reset those keybinds to Alt+2~9. 'Alt+' just shows up when I try to set it to Alt+2~9, and then it just goes back to a black space.
- I have tried resetting my keybinds to default and also restarting the game but it didn't work.
- I am able to use the Alt key and the numbers 2-9 outside of FFXIV.
- This is the first time I am having this issue with the game.
- I'm not sure if this affects the issue but I do play FFXIV on two different computers.
