When I rename a file from File Explorer, I click on an already selected file. This makes the entire filename minus the extension selected, with the cursor at the end of the filename. My renaming consists of appending something to the filename, so I press right arrow, then left arrow to unselect and bring the cursor back to the original place. Is there any short-cut for unselecting text? May also apply to the address bar in a web browser or File Explorer etc.
Edit: Just to be clear, I am asking for a one-click replacement for left-arrow, right-arrow. I want a short cut replicating left-arrow, right-arrow (if it exists). If not, I can live with pressing the two keys one after the other.
