How can I map a keyboard shortcut to "Add to dictionary"?

Hiya! First off, thanks a lot for this amazing extension, writing docs is a lot more fun with this.
I did a quick peek through the docs, but couldn't find exactly what I was looking for:
I want to make a keybinding for ltex.addToDictionary, I'm using the Vim keybindings so I would like to use my mouse as little as possible.
In Keyboard Shortcuts in VScode I made a keybinding to ltex.addToDictionary to Z-G but I get an error when I actually use it.:
Running the contributed command: 'ltex.addToDictionary' failed.

My question basically is what command is exactly run for adding it to the dictionary? When I add a word through the Quick Fix route it works fine.

The usual way to execute a quick fix with the keyboard, such as adding a word to the dictionary, is Ctrl+. (Control and period keys), Arrow-Down, and Return.

ltex.addToDictionary is an internal (undocumented) command. All supported commands are documented here. The reason why ltex.addToDictionary doesn't work for you is that it expects a list of arguments (uri with the document URI and words with the list of words to add). When running the quick fix via the context menu, VS Code supplies the arguments because the language server part (LT_EX LS) told it before what values to use in case it wants to run the quick fix. When running it via a keybinding, the arguments are missing, and the command fails.

I think VS Code is currently not exposing the list of quick fixes for a selection in the editor to allow extensions running one of them manually (e.g., by another command that has been triggered by a keyboard shortcut).

The next release will hide these internal commands from the user interface to reduce future confusion.

Thank you very much, I'll keep it in mind :D
