There's an option in Jupyter Notebooks where you can select some cells, and then hit F, which opens up a Find & Replace feature.

This shortcut doesn't work in Jupyter Lab. It's not in the Commands list and it's not in the Edit Menu (there is only Find -- and Find Next and Find Previous). Nor can I find a global (not specific to a cell selection) Find & Replace feature.

Does this feature exist? I've found old mentions of it on the internet -- has it been removed? I'm using Jupyter Lab version 1.2.3.

The Find & Replace feature was not removed, but the way it is named in the menu (simply Find...) and the UI which requires the user to click on a small arrow to access it may be confusing. Please see the GIF below which demonstrates how to use the search & replace feature:

If you need a slightly more powerful refactoring tool (i.e. distinguishing the variable scopes) you may want to check out my jupyterlab-lsp project which now includes support for the rename action (see here for a demonstration GIF).
