Low [MAC] cmd+a uses skill on ctrl button

Description of the bug:
When I have a skill on the CTRL button, pressing
- cmd + a/z/x/c/v
quickly will use the skill on the ctrl button. If you press a/z/x/c/v when the character is already at the top of the jump this bug will not occur. Must press them in quick succession.
What is supposed to happen?:
I have jump on my cmd button, and other active skills on a/x keys. So I tend to jump and press a/x to attack, but it uses my attack skill that I have on ctrl instead.
Where did you find and/or notice this bug?:
Macbook Pro 2016 using Crossover to play
A step-by-step guide to re-producing this bug (optional):
Have a skill on ctrl button. While on a mac, press CMD then a/z/x/c/v. The skill on ctrl will be used. a/z/x/c/v refers to when CMD is pressed along with any of these keys, not all together.
Extra information (optional):
I have found that this can occur even if there is no hotkey binded to cmd + a/z/x/c/v.
It does not occur when pressing cmd + other letters (as far as I have tested).
My first thought was that it was due to a hotkey on my mac but I couldn't find any hotkey that like that, that would active the CTRL key.

In my attached screenshot, when trying to do cmd (maplestory shows it as alt) + a. I intend to jump and use band of thieves. But it uses assaulter that's on my ctrl button.
This has always been occurring, even during 2nd job.

Not sure if this is smth to do with my machine specifically or with maplelegends.

 

Yeah I did that while i was 2nd job, but once i got 3rd job i had more skills, so couldn't avoid it

 

I see, if it ends up being that then all good, I can try rebind my keys to not use cmd and try get used to that. Will wait for confirmation from staff though.
