Function Reference


Send

Sends simulated keystrokes to the active window.

Send ( "keys" [, flag = 0] )

Parameters

keys The sequence of keys to send.
flag [optional] Changes how "keys" is processed:
    0 = Text contains special characters like + and ! to indicate SHIFT and ALT key-presses (default).
    1 = keys are sent raw.

Return Value

None.

Remarks

See the Appendix for some tips on using Send(). AutoIt can send all ASCII and Extended ASCII characters (0-255). To send UNICODE characters you must use the "ASC" option and the code of the character you wish to send (see {ASC} at the bottom of the table below).

The "Send()" command syntax is similar to that of ScriptIt and the Visual Basic "SendKeys" command. Characters are sent as written with the exception of the following characters:

'!'
This tells AutoIt to send an ALT keystroke, therefore Send("This is text!a") would send the keys "This is text" and then press "ALT+a".

N.B. Some programs are very choosy about capital letters and ALT keys, i.e., "!A" is different from "!a". The first says ALT+SHIFT+A, the second is ALT+a. If in doubt, use lowercase!

'+'
This tells AutoIt to send a SHIFT keystroke; therefore, Send("Hell+o") would send the text "HellO". Send("!+a") would send "ALT+SHIFT+a".

'^'
This tells AutoIt to send a CONTROL keystroke; therefore, Send("^!a") would send "CTRL+ALT+a".

N.B. Some programs are very choosy about capital letters and CTRL keys, i.e., "^A" is different from "^a". The first says CTRL+SHIFT+A, the second is CTRL+a. If in doubt, use lowercase!

'#'
The hash now sends a Windows keystroke; therefore, Send("#r") would send Win+r which launches the Run() dialog box.

You can set SendCapslockMode to make CAPS LOCK disabled at the start of a Send() operation and restored upon completion.
However, if a user is holding down the Shift key when a Send() function begins, text may be sent in uppercase.
One workaround is to Send("{SHIFTDOWN}{SHIFTUP}") before the other Send() operations.

Certain keyboards as the Czech keyboard sends different characters when using the Shift Key or with CAPS LOCK enabled while sending a character. Due to the send AutoIt implementation the CAPS LOCKed character will be sent as a Shifted character so it will not work.
Certain special keys can be sent and should be enclosed in braces:

N.B. Windows does not allow the simulation of the "CTRL-ALT-DEL" combination!

To send the ASCII value A (same as pressing ALT+065 on the numeric keypad)
    Send("{ASC 065}")

(When using 2 digit ASCII codes you must use a leading 0, otherwise an obsolete 437 code page is used).

To send UNICODE characters enter the character code (decimal or hex), for example this sends a Chinese character
    Send("{ASC 2709}") or Send("{ASC 0xA95}")

Single keys can also be sent repeated:
    Send("{DEL 4}") ;Presses the DEL key 4 times
    Send("{S 30}") ;Sends 30 'S' characters
    Send("+{TAB 4}") ;Presses SHIFT+TAB 4 times

No key is sent if the count is zero allowing the count to be set programatically:
    Send("{M " & $iCount & "}") ;Presses the M key as many times as set in the $iCount variable

To hold a key down
    Send("{a down}") ;Holds the A key down
    Send("{a up}") ;Releases the A key

To set the state of the capslock, numlock and scrolllock keys
    Send("{NumLock on}") ;Turns the NumLock key on
    Send("{CapsLock off}") ;Turns the CapsLock key off
    Send("{ScrollLock toggle}") ;Toggles the state of ScrollLock

If you wish to use a variable for the count, try
    $n = 4
    Send("+{TAB " & $n & "}")

If you wish to send the ASCII value A four times, then try
    $x = Chr(65)
    Send("{" & $x & " 4}")

Most laptop computer keyboards have a special Fn key. This key cannot be simulated.

Note, by setting the flag parameter to 1 the above "special" processing will be disabled. This is useful when you want to send some text copied from a variable and you want the text sent exactly as written.

For example, open Folder Options (in the control panel) and try the following:


Send("{TAB}") Navigate to next control (button, checkbox, etc)
Send("+{TAB}") Navigate to previous control.
Send("^{TAB}") Navigate to next WindowTab (on a Tabbed dialog window)
Send("^+{TAB}") Navigate to previous WindowTab.
Send("{SPACE}") Can be used to toggle a checkbox or click a button.
Send("{+}") Usually checks a checkbox (if it's a "real" checkbox.)
Send("{-}") Usually unchecks a checkbox.
Send("{NumPadMult}") Recursively expands folders in a SysTreeView32.

Use Alt-key combos to access menu items. Also, open Notepad and try the following:
Send("!f") Send() Alt+f, the access key for Notepad's file menu. Try other letters!


Send("{DOWN}") Move down a menu.
Send("{UP}") Move up a menu.
Send("{LEFT}") Move leftward to new menu or expand a submenu.
Send("{RIGHT}") Move rightward to new menu or collapse a submenu.
See Windows' Help--press Win+F1--for a complete list of keyboard shortcuts if you don't know the importance of Alt+F4, PrintScreen, Ctrl+C, and so on.

When running a script on a remote computer through a program as psexec (www.sysinternals.com) or beyondexec (www.beyondlogic.org) it is necessary, specially when sending strokes to a program launch by the script with a Run() function, to use ControlSend() or other ControlXXX functions to directly communicate with the control. Send() even with Opt("SendAttachMode", 1) will not work.
Using the -s mode when submitting can help to have better rights on the remote computer.

Opt("SendKeyDelay",...) alters the the length of the brief pause in between sent keystrokes.
Opt("SendKeyDownDelay",...) alters the length of time a key is held down before being released during a keystroke.
Set both "SendKeyDelay" and "SendKeyDownDelay" to 0 to remove all delays when sending keystrokes. This may be required under certain circumstances, for example, when locking the system ("#l") it may be necessary to remove the delays in order to prevent the WIN key from being stuck down.

    ; Simulate the key combination Win + R to open the Run dialogue window.

    Local $hWnd = WinWait("[CLASS:Notepad]", "", 10)

    ; Simulate entering the following string and pressing the 'F5' key to input the date and time into edit control of Notepad.
    Send("Today's time/date is {F5}")

    ; Close the Notepad window using the handle returned by WinWait.
    WinClose($hWnd)

    ; Now a screen will pop up and ask to save the changes, the classname of the window is called
    ; "#32770" and simulating the "TAB" key to move to the second button in which the "ENTER" is simulated to not "save the file"
