shortcut for accessing hidden lexeme fields

[dwhieb]

In the Lexeme Details Editor, when the user has selected to hide certain fields, it would be nice if there were a keyboard shortcut (and probably accompanying "Add Field" button) that would allow the user to quickly add a single field to the view, without having to choose "Show All Fields" or to select which fields to hide/display.

For example, if you wanted to add an etymology to just one entry, you might press Alt + Shift + = (for Alt + +) to bring up a field selector. The user start typing the name of the field they want, and can then select the Etymology field, which will be added to just the current view.
