But now, without this button, I found second way (first is ENTER on some mouse button ofc.) how to paste path from clipboard and "make" ENTER without touching a keyboard:
- slow double click on some file/directory (I advice you some at the bottom of list)
- - now we see inplace rename dialog box with confirmation button at the end
- now make slow double click on path (at top of TC dirs/files list window)
- - inplace rename dialog box ofc. disappear, but confirmation button is still with us!
- paste from clipboard (using mouse) new path and click on this lovely confirmation button
Enjoy!

And Mr.Ghisler please keep this functionality. Or can you add confirmation button (smaller ofc.) at the end of changing path dialog box too?
