After using Krita for several years, I’ve occasionally run into an issue where pressing the Spacebar jumps to another layer. I always thought it was a bug, but I finally figured out the cause recently. It turned out I was naming my layers incorrectly by adding a space at the beginning of the layer name.
I also discovered that if a layer name starts with a number or an English letter (that isn’t assigned to any shortcut key), pressing the corresponding key will also jump to that layer.
I reported this as a bug, but the developers replied that it’s not actually a bug. It seems this is just a hidden feature of Krita — one that has never been mentioned in the official Krita documentation.
That’s all.
Hello @zeiukkz and welcome to the forum 
This was described in a topic here:
How to disable select layer by name?
A bug report was raised and your later bug report was linked to it because it was the same ‘bug’ being reported.
That might be an oversight that needs to be corrected by adding the information to the manual.
This isn’t a hidden feature of Krita’s layer list, this is just a normal behavior of any tree view, list view or combo box in all of Krita and many other applications: when you type into them, it selects a matching element. If I type e.g. into the bookmarks dialog tree in Firefox or into the files listing in my file manager or similar, I get the same behavior.
Whether this should be in the manual is debatable. Evidently people don’t understand this feature, so that’s arguably a reason to put it in. On the other hand, it’s not the Krita manual’s job to explain common desktop functionality, we’d arguably also have to explain stuff like accelerators (Alt + a letter to actuate menus/buttons/form fields) or similar.
Either way, you can contribute to the manual at https://invent.kde.org/documentation/docs-krita-org/. If someone writes something from it, that inclusion can be discussed.
I got it. Thank you for your reply.
Thanks for letting me know someone has already brought up this question. I appreciate your reply.
