Excel diverges most on the Mac. F4 for absolute references is Cmd+T there, and a few Ctrl combinations stay Ctrl rather than becoming Cmd.

Reading the key names

Keys joined by + are pressed together: Ctrl+Shift+P means hold Ctrl and Shift, then P.
On a Mac, Cmd is ⌘, Option is ⌥ (labelled Alt on some keyboards), Control is ⌃ and Shift is ⇧.
Windows Ctrl usually becomes Cmd on a Mac, but not always — this reference lists both combinations separately.
With a Korean, Japanese or Chinese input method active, shortcuts built on letter keys may not fire. Switch to Latin input and try again.
When a combination does nothing, another program has often claimed it as a global shortcut first.
