@isidorn is there a usual way to access a tooltip via keyboard that we should be following?

[isidorn]

@alexr00 yeah, cmd + k, cmd + i. Works for all editor hovers. Make sure that when user access the tooltip like this that the focus is moved inside the tooltip - so the screen reader would read the proper thing

[alexr00]

I have added the ctrl + k, ctrl + i keyboard shortcut for extension tree hovers. However, when the hover is escaped, focus does not return to the tree as I think is correct. @Tyriar, is there an option I am missing when using focus = true for ensuring that focus is returned to the previously focused element when the hover is escaped?

[isidorn]

@alexr00 great, thanks! Looking at the code it does not look like focus is passed to the hover (I might be misinterpreting). Is it possible to move the focus to the custom hover when this command is triggered by keybinding?

[alexr00]

Focus is passed to the hover. I confirmed that NVDA reads the hover when shown via the keybinding.

(its this true that does it:

vscode/src/vs/workbench/api/browser/viewsExtensionPoint.ts

Lines 301 to 302 in 25b2357

	}, true);
	},

)

[isidorn]

Thanks! I missed that true.

@alexr00 I don't think there's a mechanism for returning focus, I guess we'd want to check how the quick pick does it and adopt that in the hover service.
