 ## Last key pressed
 
-"Last key pressed" expression returns the last key press in the form of a string. For example, if the last key press is the left arrow key, the expression will return "Left".
+"Last key pressed" expression returns the last key press in the form of a string. For example, if the last key press is the left arrow key, the expression will return "Left". If the last key pressed has no name known to GDevelop, the expression returns an empty string.
+
+## Key names
+
+The "Key pressed/released (text expression)" conditions and the "Last key pressed" expression use the key names below. These names are **case sensitive** — in particular letter keys are **lowercase** (`"a"`, not `"A"`).
+
+- **Letters**: `a` to `z`
+- **Top-row numbers**: `Num0` to `Num9`
+- **Numpad numbers**: `Numpad0` to `Numpad9`
+- **Numpad operations**: `Add`, `Subtract`, `Multiply`, `Divide` (and the location-specific `NumpadAdd`, `NumpadSubtract`, `NumpadMultiply`, `NumpadDivide`, `NumpadReturn`)
+- **Arrows**: `Left`, `Up`, `Right`, `Down` (numpad variants: `NumpadLeft`, `NumpadUp`, `NumpadRight`, `NumpadDown`)
+- **Modifiers**: `LShift`, `RShift`, `LControl`, `RControl`, `LAlt`, `RAlt`, `LSystem`, `RSystem` (the Windows/Command key), `Menu`
+- **Navigation**: `PageUp`, `PageDown`, `End`, `Home`, `Insert`, `Delete` (numpad variants: `NumpadPageUp`, `NumpadPageDown`, `NumpadEnd`, `NumpadHome`)
+- **Editing/whitespace**: `Space`, `Back` (Backspace), `Tab`, `Return` (Enter), `Escape`
+- **Punctuation**: `SemiColon`, `Comma`, `Period`, `Quote`, `Slash`, `BackSlash`, `Equal`, `Dash`, `LBracket`, `RBracket`, `Tilde`
+- **Function keys**: `F1` to `F12`
+- **Other**: `Pause`
+
+!!! tip
+
+    The left/right modifier keys (like `LShift`/`RShift`) are distinguished by their physical position. If you don't care which side was pressed, you need to check for both.
