Polarity Community Edition users can make use of system-wide shortcut keys that make it easier to run an on-demand search of their clipboard contents or toggle highlight mode on/off.
The shortcut key bindings are slightly different depending on the OS that you're using.

On-Demand Only Shortcut
On Windows and Linux, you can highlight text and then trigger an on-demand search with the shortcut key: CTRL + C (Hold)
On macOS, you can highlight text and then trigger an on-demand search with the shortcut key: Command + C (Hold)
macOS users will need to enable accessibility settings for Polarity to enable shortcut keys.
