Bug 149195 – Web Inspector: Command-Enter in Debugger should show a popover with evaluation result

• Component: Web Inspector
• Status: RESOLVED FIXED

[Nikita Vasilyev]

I've been using Command-Enter in Debugger (https://bugs.webkit.org/show_bug.cgi?id=148368) for a few days and I'm not very satisfied.

I think Command-Enter should show the exact same popover as on hover. The current behavior, evaluating in the console, is too disconnected 
from the source code and requires an extra mental effort to keep the context.

I also accidentally improved keyboard navigation for type profiler. Command-Enter shows popovers with type information too.

Currenty, the only way to display the popover is to hover over the text with a mouse cursor. Provide a way to display it via a keyboard shortcut, Command-Enter.

Oops, this patch has been gathering dust far too long, sorry about that. I don't know the CodeMirror integrations well enough to review this. Joe or Tim (or Devin), can you take a look?

Seems this would add complexity for a very hard to discover feature. Is there some way we can make this more discoverable, otherwise I fear it wouldn't be used much?

I don't think it's that different from the rest of keyboard shortcuts. Also, Command-Enter already evaluates selected console message: https://twitter.com/ELV1S/status/636431257379864576.

Eventually, we will have a page with all shortcuts. I'll also write a blog post, too.

I think this shortcut isn't that hard to remember. Certainly easier than Chrome's Control-Shift-E, which evaluates selection in the console.

I don't think we should give up on keyboard accessability only because it adds complexity. This patch levereges existing mouse over handling.

I had to add WebInspector.CodeMirrorTokenTrackingController.TriggeredBy.Keyboard to avoid hiding the popover on mouse move. When we show the popover on mouse hover, we hide it when there is a mouse movement outside of evaluated token. It didn't work well with Command-Enter and I had to add WebInspector.CodeMirrorTokenTrackingController.TriggeredBy.Keyboard.
