this keyboard is not work ,i don't kown why,can you tell me? firefox 64.0 (64 位)

Hello sky-gg,

You give us little or no information as to what exactly it is that doesn't work ..... (?)

Clear the object inspector pane Esc

Are you having problems with the keyboard shortcuts that are listed here :

https://developer.mozilla.org/en-US/docs/Tools/Keyboard_shortcuts

You (probably inadvertently) marked my post as Chosen Solution, instead of answering my questions ..... (?).

You can remove that Chosen Solution mark by clicking on the 'Undo' button to the right of that post - if you don't, others might ignore your post, as they'll think that your problem has been solved

When the Inspector is open then ESC should toggle the Web Console on/off.

What keys aren't working for you?
