A keybinding when-clause for looking up the position of windows like the panels

[leighmcculloch]

Could the ability to write "when" expression based on position of windows like the panels be added?

I'm needing this because when the panels are on the right side I want to have different keybindings as when it is on the bottom. I'm mirroring TMUX bindings so when I press CTRL-A H when the panel is on the right I want it to move to the editor, but at the bottom I want it to move to split terminals.

I looked in the source code and discovered there is already a context that provides this, panelPosition. It's defined here:

vscode/src/vs/workbench/common/panel.ts

Line 11 in fc9ff5d

export const PanelPositionContext = new RawContextKey<string>('panelPosition', 'bottom');

This context is not included in the documentation however, so maybe it should be added there. See:
https://code.visualstudio.com/docs/getstarted/keybindings#_when-clause-contexts

Is there anyway to programmatically list all the available contexts for updating the documentation?

It may not be a direct answer to your question but should help in the future, see https://stackoverflow.com/a/62202897/836330

By following those steps you could see a panelPosition: "bottom" context key for example. You would have to scroll through the list and see if something was on point.

@ArturoDent Thanks for replying and for providing the StackOverflow link, that was really helpful. As I noted above (#111974 (comment)) I found the solution, to use the panelPosition context key, and it is working perfectly! I'll use the developer options tip that you linked to next time.

I think this issue should probably be converted into a documentation issue. It's odd that the official documentation provides a non-exhaustive list of when-clause contexts. Is there a reason the list cannot be exhaustive given that the values are in the code and could be extracted?

Alternatively, there could be information in the official docs about how to use the developer options to identify when-clauses.

There's is an open issue for autocomplete in vscode repo #9303. And I think there are multiple issues in https://github.com/microsoft/vscode-docs for documenting all context keys.

Thanks! Sounds great. I'll close this then.
