Windows 10: Keyboard Shortcut Issues on ASUS TUF Laptop: Ctrl+Z and Ctrl+Alt+Delete Not Working

A few hours ago, after playing a game that required frequent use of the Ctrl key, I noticed that some of my commonly used keyboard shortcuts had stopped working, particularly Ctrl+Z for undoing actions. Instead of functioning normally, pressing Ctrl+Z types a "z". Additionally, other shortcuts that use the Ctrl key, such as Ctrl+Alt+Delete, no longer work, while others such as Ctrl+C and Ctrl+V still function properly. I used the on-screen keyboard to diagnose the issue. When performing a working shortcut like Ctrl+C, the on-screen keyboard indicates that the Ctrl key is held down as expected.

Ctrl+Shift+Z shortcut unassignable

Here are the quick answers to your questions, and following, a more develop explanations.

1. Ctrl+Shift+Z is an already existing basic, known shortcut in all Adobe softwares for the "Redo" action. I am trying to use it and it’s not doing anything. Ctrl+Alt+V is a shortcut I am trying to assign to an action in the ebook conversion software Sigil.

2. Ctrl+Shift+Z for the already existing shortcut of the "Redo" action in Adobe softwares. Ctrl+Alt+V to a specific function in Sigil.

3. Ctrl+Shift+Z in all the Adobe Creative Suite, Ctrl+Alt+V in Sigil.

Actually the issue happened when I started my work on InDesign yesterday. As you must know, Ctrl+Shift+Z is a very common, basic shortcut for the "Redo" action. After that, I opened up Sigil and tried to assign Ctrl+Alt+V to a certain action, which is the
setting I put previously in my old laptop using Windows 8.

Then, when I noticed both didn’t work, I opened a software that makes me able to remap my keyboard and assign new keystrokes, key combinations, or even macro, to a single key (SteelSeries software going with my MSI gaming laptop), and tried different key
combinations. I saw that Ctrl+Shift+A was fully detected for exemple, but if I press Ctrl+Shift+Z or Ctrl+Alt+V, the software only detects Ctrl+Shift or Ctrl+Alt, and not the letter going to it.

Here is a screenshot of some tests I did in the SteelSeries software, testing key combinations. I tried Ctrl+Shift combined with respectively those letters, in this order: w / x / y / z

As you can see, the combinations with the W and with the Y are detected, but with the X and the Z, they aren’t. And if I tried to assigned as shortcut the combinations with the X and the Z in any software, they are also not detected.





Also, Ctrl+Alt+V is not detected anywhere as mentioned, but Shift+Ctrl+V is detected. Ctrl+Alt+Z and +X are also not detected. But any letter with only Ctrl, only Shift or only Alt are detected.

So the issue is happening in multiple softwares and seems to come from some letters not being detected when used in combination with Ctrl+Shift or Ctrl+Alt. Very weird.... I hope my explanations are clear.

 

Ctrl+Z not working properly

In excel, when I press ctrl+z, instead of undo it will go to the top of the page and delete a random cell. At this point there is no restoring what it just did. The undo and redo buttons are grayed out. This happens no matter which file I have open. If I manually press the undo arrow instead of ctrl+z it works as intended. How can I fix my ctrl+z since I love my keyboard shortcuts. By the way ctrl+z works fine in word, it's just excel that I'm having this issue. Please advise.

 

Undo and Redo Shortcuts (Ctrl Z and Ctrl Y) NOT WORKING

I noticed the issue few days ago when the Ctrl Z stopped working on Anki but I'm not sure when it exactly started. Then I discovered that Ctrl Z and Ctrl Y stopped working on all my applications. Other shortcuts that I use usually are still functioning except
for these two.

I reformatted (removed all software except personal file) my PC yesterday but the issue still remains. I even tried different keyboards.
