`FileDialog` keyboard nav is broken

[albinalm]

Is your feature request related to a problem? Please describe.
I try to save a file and are almost required to move hands from home row to use mouse or arrow keys in my TUI app. The point of a TUI is to have a rich interface that is keyboard friendly.

Describe the solution you'd like
Add support to vim motions or optional keybind overrides to keep navigating using home row

Describe alternatives you've considered
Design my own component for opening/saving files/directories

Focus should default to the path text field which supports tab autocomplete.

So if you set the current path or a sensible root then it should be no slower than typing any other path on command line.

If that isnt working for you then its a bug.

The KeyBindings system allows you to change which keys trigger which commands and would allow you to set whatever keys you want.

Believe you can also do this system wide with the ConfigurationManager system

But if you tab to the <Tree button then navigating the tree is only supported with mouse or arrows at the moment.
I'll look into the keybindings system

I'm gonna just go ahead and apologise now for all fo this because it's my bad. I did a lot of updates to FileDialog a bit back and was not very careful in testing. I broke a bunch of things and didn't realize it, including keyboard nav.

This too:

• OpenFileDialog only closes after clicking Cancel or OK three times. #4950

I'd appreciate all the help y'all can provide in fixing these issues as I'm currently occupied elsewhere.

Here's what I see broken:

• Alt-T doesn't open/close the Tree even though it's _Tree unless the button is focused
• Alt-C should cancel since the button is _Cancel. But ESC does work.
• Tab/Shift-Tab navs everywhere fine.
• arrow keys etc, while the tree is focuse cause it to grow in a wierd way, but work.

What else?

At least some of these are v2.0.0 release blockers.

This is with 5281 - I've not yet bumped package as I see theres more changes to TreeView on the way

Good

Tab autocomplete seems to work correctly
Cycling tab auto complete options also works perfectly
Deleting characters restores append auto complete option nicely
Column sorting works
Typing letters navigation in treeview and tableview work

Bad

• File types combo box seems to be clipping:

• SpinnerView does not seem to spin when view is searching e.g. go to c:\ and search for 'e'

• Somehow you cannot tab to Cancel or Tree

• Open and collapse tree view with mouse resizes view oddly especially combined with moving slider
