Expand and reformat "Commands and Shortcuts" section in "Workflow Editor" article

[banchan86]

Fixes #108. This PR expands and reformats the "Commands and Shortcuts" for improved readability. At the same time it adds some commonly used shortcuts that are missing. The list of changes:

• Rename commands to actions
  • For a visual language, actions might make more sense than commands
• Adopt pipe table
  • More established pattern for finding actions and keyboard shortcuts
  • Uses less space, especially if we want to add more shortcuts
• Shorten actions names
  • Uses imperative style (link instead of linking)
  • Drops articles (maybe a bit controversial but I feel including them is unnecessarily wordy)
• Split point-and-click actions from keyboard shortcuts
  • Easier to distinguish between them
  • A bit unsure about where to put keyboard modifiers that affect point-and-click actions, but for now I have opted to group them together with the Point-and-Click column
• Shorten and simplify sentences
  • I have kept most of the verbiage in the Point-and-Click column (maybe necessary for novices)
  • Reduced wording in the Keyboard Shortcuts column (fits established patterns, not necessary for more experienced people)
• Format content for consistency
  • Some of the actions make explicit reference to a panel while others did not, I have added a panel item to all
• Add some missing shortcuts

@RoboDoig requested you as a reviewer because I hear you're really fast at live demos 😄 Could you check if I missed any keyboard shortcuts or if you'd like to tweak the list?

@banchan86 This is definitely needed, thanks! I will review more carefully, but one thing that jumps to mind is having the keyboard shortcuts column to the side might make it simultaneously more confusing and less visible.

I wonder if we should just have one of these tab interfaces where people can pick which modality they want to consult (keyboard or mouse) and have a separate table for each? This might also make it possible to solve more cleanly your issue with key modifiers in the mouse interface.

Otherwise we can do like VS code and keep all the shortcuts in a handy PDF cheat sheet: keyboard-shortcuts-windows.pdf
