System Information
Operating system: Windows
Graphics card:

Blender Version
Broken: (example: 2.80, edbf15d3c0, master, 2018-11-28, as found on the splash screen)
Worked: (newest version of Blender that worked as expected)

Short description of error

Press F3, type "gltf" to show "file -> export to gltf" as the first option
Press enter in the resulting dialog.

Sometimes, the second press of enter saves the file, other times it does nothing. Further presses of enter do nothing and I have to use the mouse to click on the "export gltf" button in order to proceed.

As someone who is frequently exporting to gltf and would like to do so habitually (without having to aim a mouse cursor) this is inconvenient.

Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).

Here I have always been able to confirm saving when pressing Enter.

Could you try find out what other stuff you have done when the file dialog is open and cause it to lose focus so we could replicate the problem? Thanks!

Thanks for the quick response, @ChengduLittleA.

One thing I'm noticing as I try to reproduce this bug is that it appears to depend on the position of my mouse cursor when I press enter. If my cursor is within the "Blender File View" dialog box, then pressing enter does work. However, if it's not, then pressing enter appears to do nothing.

I'm also noticing that if my mouse is hovering over any kind of widget within the dialog box, pressing enter while above it has the same effect as clicking on it: e.g. it toggles a checkbox, expands/un-expands a collapsible area, and so on. This is counter to my expectation from using other apps that support keyboard accessibility on Windows, where use of the keyboard doesn't depend at all on the current location of the mouse cursor.

Is this some kind of setting that I've accidentally enabled?

Also, FWIW, I am on Blender 3.5.1 from 2023-04-24 18:11.

If my cursor is within the "Blender File View" dialog box, then pressing enter _does_ work. However, if it's not, then pressing enter appears to do nothing.

Ahh I see. Indeed I can replicate the problem now.

I think this might be a limitation of the window manager and widgets in Blender. Will poke developers about it.

The mouse needs to hover the File Browser so it responds to events. To a degree it's a limitation of the current implementation: proper modal windows with event capturing would have to be supported on all OSes. But it's also a design question of how far we want to go towards modal dialogs, which could be argued violate our non-blocking design paradigm.

Mouse hover based focus on widgets is also a long standing Blender feature that many people appreciate. It indeed gets in the way at times, it's a trade-off. Arguably making enter presses act the same as a mouse click is taking it a bit too far, but that is a bigger design discussion as well.

So closing as there is no bug here as far as I can see, more like design trade-offs or known limitations. Thanks for the report nevertheless.
