Drill all 67 until you don't have to think about them.
the same key, a different pane
macOS/Windows factory (default) hotkeys for Houdini, viewport plus network editor; excludes mouse/drag navigation (Space+LMB tumble, wire-cut, node-copy) and generic OS copy/paste/undo/delete since those can't be drilled on a keyboard; every shortcut is remappable via Edit > Hotkeys, so verify against your target major version.

Every deck is graded 1 to 6: level 1 is the reflex core, the top level is where the specialists live. One move from each, so you can see how far it goes.
You need a new node in the current network and don't want to hunt through menus
The tab menu is how nearly every node gets born; the reflex pays off thousands of times a session.
…and 3 more at this level
The viewport camera is somewhere strange and you want the default home framing back
A known-good camera is one keystroke away instead of a manual reset.
…and 12 more at this level
The selected node has its own custom handles and you want them live in the viewport
Jumps straight to a node's bespoke gizmo instead of editing values in the parameters.
…and 16 more at this level
You want to jump into the UV editing viewport
Sends you to UV space without reconfiguring a pane by hand.
…and 12 more at this level
Tumbling is orbiting the wrong spot and you want the pivot on the point under the pointer
Re-anchors your orbit so close-up work stops swinging out of frame.
…and 12 more at this level
You want to jump the playhead to the previous scoped keyframe
Hops between the keys that matter instead of scrubbing frame by frame.

How graduation works. Drill until every move in the deck holds at ≥95% first-try, under 800ms median, across two separate days. Then the deck is done — and you get a certificate stating exactly that, plus a LinkedIn credential in one click.
