Entering the Popup Documentation Window (to select text etc.)

[d-mceneaney]

When programming and using a language server in Neovim, one can hover over a text item using "shift + k". This will display a pop-up window containing documentation (if available) for the word under the cursor position.

The user can then press "shift + k" a second time to "switch into" the documentation window as if if were a regular buffer.

Once inside the popup window, the user can then move around and select & copy any text etc.

It does not appear that Helix has this capability so I thought I might add an enhancement request here in case anyone has time to review and deems it worthwhile to implement. Thanks.
