Describe the project you are working on

Any project

Describe the problem or limitation you are having in your project

Sometimes I walk through the filesystem tree with the arrow keys and I want to delete multiple files at once. There's no way to do it without grabbing the mouse because shift only works with a mouse click

Describe the feature / enhancement and how it helps to overcome the problem or limitation

Allow holding shift to select multiple items with arrow keys, like in all other apps

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

If this enhancement will not be used often, can it be worked around with a few lines of script?

N/A

Is there a reason why this should be core and not an add-on in the asset library?

Basic editor usability/accessibility
