Rename file using "Tab"

[Delahoya88]

Hello,
I usually change a large amount of file names manually because each file has its name and I spend a lot of time changing it.
When I am browsing over the thumbnails, I want when I press the "Tab" key to go to the next file, but it is configured to go to the file below.

Is there another possibility?
Thank you

no 'Tab' is standard key to go to next row

And is there a way to go to the next file using the keyboard and not the mouse?

Thank you!
