Welcome to Liquid!
To use Liquid select text, do the Keyboard Shortcut (default is ⌘-shift-2 or command @) and choose a command through quick keyboard shortcuts (or mousing around, as you learn the shortcuts):
For example: R for References then W for Wikipedia.
To change the Keyboard Shortcut to the more convenient ⌘-space (or anything else you prefer):, open System Preferences, click on Keyboard, make sure you are in the Shortcuts tab, then, in the column on the left:
1 Click on Spotlight and disable ⌘-space
2 Click on Input Sources and disable ⌘-space if it is active there.
3 Click on Services, scroll down to Liquid and double-click on the current Liquid shortcut and set it to be ⌘-space
IF you have more than one input source (such as different languages) Click on Sources and disable ⌘-space. I have no idea why Apple has made this shortcut the same for Spotlight and Choose Input Source, but such it is.
To Add a Search. If you have upgraded Liquid, you can add any search engine you like:
Speed Tip. Instead of Search/Google, just hit ‘enter' to search Google and ‘shift-enter’ to go to the first item on Google search. Hit 'spacebar' to Copy/As Citation from the web.
Problem? Please restart to register Liquid as a Service if the keyboard shortcut doesn't work.
