[FR] Add a shortcut key for selection in the App

Proposal Summary

My suggestion is to use a shortcut key for selection in App.

Motivation

Selecting a sample is repeated many times during dataset cleaning. Currently, in both grid view and expanded view cases, selecting a sample is done by clicking on the little box at top left of a sample. This serves the purpose but is not easy to do for many samples.

What areas of FiftyOne does this feature affect?

• App: FiftyOne application
• Core: Core fiftyone Python library
• Server: FiftyOne server

Details

In a typical OS, in file explorer, we do this by clicking anywhere on file/thumbnail. It would be nice if same habits can be transferred to Fiftyone, but 'click on sample' is already reserved for "Click to Expand" in Fiftyone.

My suggestion is to use a shortcut key for selection in App. When that key is pressed,

• the sample under the cursor can directly be selected or
• "click to expand" mode can switch to "click to select"
