Intro
After Effects on Mac uses Command as its primary modifier throughout, with Option for secondary variants. A handful of shortcuts use Control instead, mostly numeric-keypad alternates and a few Opacity/Scale nudges.

After Effects on Mac uses Command as its primary modifier throughout, with Option for secondary variants. A handful of shortcuts use Control instead, mostly numeric-keypad alternates and a few Opacity/Scale nudges.
Non-numpad alternates. Several numeric-keypad shortcuts (audio-only preview, alternate preview, marker placement) have an extra Control-based alternate on Mac for keyboards without a numeric keypad, something Windows doesn't offer since it doesn't need to.
A few Opacity and Scale shortcuts use Control, not Command. Increasing or decreasing Opacity by 1% or 10% on the numeric keypad uses Control+Option rather than the usual Command+Option pairing. Scale shortcuts, by contrast, do use Command as expected.
Option+W is a shared toggle. Option+W activates and cycles between the Roto Brush and Refine Edge tools, the same chord for both, matching Adobe's own reference.
The After Effects Mac shortcut list is available as a printable PDF. Given its size, the property-revealing single letters (P, R, S, T, A) and the keyframe-easing shortcuts (F9, Shift+F9) are worth learning first.
For several of them, yes, Adobe documents a Control-based alternate on Mac for keyboards without a numeric keypad. For example, Toggle Mercury Transmit video preview is NumpadDivide or Control+/ on Mac, but only NumpadDivide on Windows.
Adobe's own shortcut reference documents it that way for the numeric-keypad Opacity increase/decrease shortcuts specifically, Control+Option+Plus or Control+Option+Minus. The equivalent Scale shortcuts use Command as expected, so it's specific to Opacity.
TT shows only the Mask Opacity property for the selected layer in the Timeline panel, distinct from a single T press, which shows Opacity (or Intensity for lights).
