Prebuilt Modifier Combos in Basic Key List

Idea: Add modifier key combos to the Basic key list (grouped with the existing single-key modifiers)

Expand the Basic key list to include common modifier combinations (⌘⌥, ⌘⌃, ⌥⌃, ⌘⌥⌃, Hyper, etc.) as default/pre-built keys. That way, Actions can be built by selecting a single modifier combo instead of adding each modifier one by one.

Productivity gains + improved UX

• Hyperkey ‘Actions’ reduced from 9 steps —> 3 steps

• This would remove 16 steps from the Framer preset found on Input

• Remove need for redundant tedious steps

Optimize most common use case format (modifier[s] + key)

• Consistent process for most common use-case regardless of modifier key combo

• Reduce repetitive setup at system level

Better readability + debugging

• Actions are easier to understand at glance (good for community)

• Easier to debug, revise in future

I confirmed that this method sends the expected key codes via Karabiner Event viewer.
i.e. Sample action below sends 5 down keys following by 5 up keys.
