问题
I'm looking for a way for vscode to tell me the command name for a keybinding. For example, cmd+a maps to editor.action.selectAll, so ideally I'd press a keyboard shortcut, then cmd+a, then VSCode could tell me editor.action.selectAll.
As a partial solution, I can open my keybindings.json and search for cmd+a, but this doesn't work for extensions - my particular use case is figuring out what the vim o command is called so I can remap it.
In the Emacs world, this functionality is available under describe-key (C-h k).

You can find the command associated with a key binding by typing the keybinding into the Keyboard Shortcuts search box:
Unfortunately, per the source code, the vim extension doesn't use this mechanism to bind the o key.
Fortunately, it does let you rebind the keys in settings. First, open settings (F1 Preferences: Open Settings), then add (to bind i, for example):
"vim.normalModeKeyBindingsNonRecursive": [
"before": ["i"],
"after": ["o"]
],
If you have the new settings UI, you might need to search for vim.normalModeKeyBindingsNonRecursive first, and then click Edit in settings.json.

As of the September 2018 release, VSCode can do this from the keyboard shortcuts window.
From the keyboard shortcuts window (cmd+k cmd+s), type cmd+option+k or click the keyboard icon on the right.
Kudos to this comment linking to this approach as an answer to another question.
