Shortcut `Control+I` and `Control+O` don't work on macOS Big Sure #370

<!-- Describe the issue -->

Expected behavior

Using shortcut Control+C and Control +O from main screen and from Node window (called via Control+I as an example) to open Debug log file(Control +O) and Console Control+C

Actual behavior

To open Debug log file(Control +O) and Console Control+C Control+I Control+N Control+P work as expected.

I think your expectations are wrong. The actual shortcuts on macOS are as pictured on the following screenshot:

Please note, that ⌘ is the Command key. If you are using non-Apple keyboard, it could be mapped to the Windows key.

UPDATE.

Specifically to a mnemonic shortcut bound to the "Open" button (to open a debug log file) -- from Qt docs:

On Mac, shortcuts are disabled by default.

@kolya182 did this solve your issue: #370 (comment)

The commands are prefixed with command, not control, for macOS

Actually UI is misguiding, especially underscored capitalized first character points to that <img width="1435" alt="Screen Shot 2021-07-05 at 9 27 10 PM" src="https://user-images.githubusercontent.com/3277207/124542316-087cc080-ddd8-11eb-9be2-c3f243e95aad.png">

@kolya182 the screenshot you posted is using the Qt Fusion style which we introduced in #177 because of visual bugs with the version of Qt we were using at the time, see: #136.

macOS disables mnemonics and so its style factory doesn't show them. The Fusion style is more of the Linux style, so the mnemonics are shown when using that style factory.

The usage of Fusion style was reverted in #246 after bumping our Qt version to 5.12.10. The next Bitcoin Core release will not have these misleading underscore

Thank you for explaining, will wait for new release. You can close in this case.
