[TreeBrowser] Allow right arrow key to open files

[advice2020]

I was wondering if it would be considered to add a setting that would allow your right arrow key to open items under the cursor/highlight.
Right arrow on folders = expand folder (current behavior)
Right arrow on files = open that file in Geany tab (same action as when you hit enter, but a little more convenient because hand is already on arrow key section of keyboard)

Thank You
