Ctrl+F6Mac
Cmd+F6Edits the parameters, their order, the return type and the name in one dialog, and updates every call in the project to match — like rename, it touches files you do not have open. Whatever default you type for a new parameter is what lands at each call site.

IntelliJ IDEA ships a different default keymap per platform, and two of them on macOS — "macOS" and "macOS System Shortcuts" — so when nothing works, look at Keymap in Settings first; whichever you pick then serves PyCharm, WebStorm, GoLand and Android Studio unchanged.
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.
