Add keyboard shortcuts for FlowBox navigation

Enter now activates the currently focused FlowBoxChild to copy the emoji to the clipboard.
The c key returns focus to the category bar while navigating through the FlowBoxes.

Hello @Ano-sys , thanks for the contribution!

I tested the changes and noticed a couple of things:

• Previously, pressing Esc would just hide the OmniGlyph window and keep the app running in the background. With this change, Esc now closes the application completely via _close_window(), so the behavior is different from before.

• The Enter key functionality is working as expected.

• The c key doesn't seem to be working on my end. Pressing c doesn't open or focus the category bar.

Could you have a look?

Hi, I wrote a comment under the issue to explain my view on the escape behavior.

For c the focus is moved not to the main category bar with Emoji, Emoticons, Arrows, ..., instead the emoji category selection is focused. I fond myself stuck in the lower emoji selection, when navigating with the keyboard, this was a fast and easy solution to escape the capture int the FlowBox.

Thanks for clarifying.

I see what you mean now. The c shortcut is moving focus to the emoji category selector rather than the main collection sidebar. The Enter functionality works well, but I would like to think a bit more about the c shortcut and whether that's the best keybinding and navigation flow before merging.
