How can the extension be hidden when editing a filename via F2?

[Andreco]

I searched all over the web and inside the many Configuration options, but I can't find a solution to only see the filename (without extension) when editing via F2. Now, F2 highlights the name but no the extension; however, I often have to change only the end of the filename, and then the extension gets in the way. Any way to do this? Thanks!

You mean inline rename.  No but only filename part is preselected.. and pressing -> arrow will move cursor to last char in filename before extension.
you can also quick select extension with Ctrl+E
