Function Reference
Send
--------------------------------------------------------------------------------

Sends simulated keystrokes to the active window.

[autoit]

Send ( "keys" [, flag] )

[/autoit]

Parameters

keys The sequence of keys to send.
flag [optional] Changes how "keys" is processed:
flag = 0 (default), Text contains special characters like + and ! to indicate SHIFT and ALT key-presses.
flag = 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 to "!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 to "^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 keyboard as the Czech one send different characters when using the Shift Key or being in CAPS LOCK enabled and sending a char. Due to the send AutoIt implementation the CAPS LOCKed char will be sent as Shifted one 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 repeated, e.g.
Send("{DEL 4}") ;Presses the DEL key 4 times
Send("{S 30}") ;Sends 30 'S' characters
Send("+{TAB 4}") ;Presses SHIFT+TAB 4 times

The key will be send at least once even if the count is zero.

To hold a key down (generally only useful for games)
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 (https://autoit.de/www.sysinternals.com) or beyondexec (https://autoit.de/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) is not working.
Using the -s mode when submitting can help to have better right 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.

Send is quite useful because windows can be navigated without needing a mouse.

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

[autoit]

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.
