Name
IsKeyDown -- check if a key is pressed (V1.5)
Synopsis
state = IsKeyDown(key$[, rawkey])
Function
This function checks if the key specified by key$ is currently pressed. If it is, this function will return True otherwise it will return False.

key$ is a string representing a key on your keyboard. This can be one of the following control keys:

‘UP’
Cursor up
‘DOWN’
Cursor down
‘RIGHT’
Cursor right
‘LEFT’
Cursor left
‘HELP’
Help key
‘DEL’
Delete key
‘BACKSPACE’
Backspace key
‘TAB’
Tab key
‘RETURN’
Return key
‘ENTER’
Enter key
‘ESC’
Escape
‘SPACE’
Space key
‘F1 - F16’
Function keys
‘INSERT’
Insert key
‘HOME’
Home key
‘END’
End key
‘PAGEUP’
Page up key
‘PAGEDOWN’
Page down key
‘PRINT’
Print key
‘PAUSE’
Pause key

Alternatively, key$ can also be a character from the English alphabet, e.g. "A", or a string containing a number from 0 to 9. Note that IsKeyDown() doesn't support Unicode keys.

Starting with Hollywood 4.0, you can check the status of the modifier keys, too. The following modifier keys can be checked using IsKeyDown():

‘LSHIFT’
Left shift key
‘RSHIFT’
Right shift key
‘LALT’
Left alt key
‘RALT’
Right alt key
‘LCOMMAND’
Left command key
‘RCOMMAND’
Right command key
‘LCONTROL’
Left control key
‘RCONTROL’
Right control key

Starting with Hollywood 6.1 you can pass the special string ANY in key$ to check for an arbitrary key to be pressed.

Starting with Hollywood 7.1 there is an optional argument rawkey. If this argument is set to True, IsKeyDown() will treat key$ as a raw key and check if it is down. In that case, key$ must be one of the raw keys defined by Hollywood. See Raw keys for details. The difference between normal keys and raw keys is described in the documentation of the OnRawKeyDown event handler. See InstallEventHandler for details.

Inputs
key$
key to check
rawkey
optional: True if key$ is a raw key (defaults to False) (V7.1)
Results
state
True if key$ is pressed, False otherwise
Example
Print("Press F1 please.")
Repeat
  VWait
Until IsKeyDown("F1") = True
The above code waits until the F1 key is pressed. (you can have that easier by using WaitKeyDown(); the one above is only useful if you want to do something while the key is not pressed)
