Ok, I'm exactly what you wrote about, but not only for the function jumps - for rest of the cases as well.
For example, when I click on the item in the Outline plugin sidebar, my cursor jumps to a new position (jumps some code). So, it would be very useful to have a keyboard shortcut, which would allow to jump the cursor back to it previous position. Many other scenarios might be involved as well.
Is it difficult to implement such feature?
Thank you!
