I cant find anyone else also complaining about this which surprise me.
Ps is wicked when I use lots of keyboard commands, like press L= lasso or moving around with space bar, that’s the worst, it can change my tool and orientation!
S= stamp tool, can make select menu come down instead etc…
And strangely this seem to be random! mostly the buttons work and I get the tool I want.
This behavior I have had for say 8 years, different PC:s and PS versions.
Cant find much on google.
Is it something wrong with me then?? 
Have you experienced PS disturbed in this way like me?

I just now discovered, part of the problems is from an “alt” key toggle, that underlines the top menus. Because alt+scroll, is the default "zoom for me. so I use it alot, I cant find how/if you can disable this though.

I personally prefer using the CTRL + or - for zooming in and out…
Maybe your keyboard is sticking or something underneath the spacebar is catching the alt sensor thus changing the tool you are trying to use?
