: [[_SCREENPRINT]] {{Parameter|text$}}


{{PageDescription}}
* [[Keywords_currently_not_supported_by_QB64#Keywords_Not_Supported_in_Linux_or_MAC_OSX_versions|Keyword not supported in Linux or MAC versions]]
* {{Parameter|text$}} is the text to be typed into a focused program's text entry area, one character at a time.
* Set the focus to a desktop program by using the [[_SCREENIMAGE]] handle as the [[_SOURCE]]. Use the image to map the desired area. 
* [[_SCREENCLICK]] can also be used to set the focus to a program's text entry area on the desktop.
*'''Note: If the focus is not set correctly, the text may be printed to the QB64 IDE, if open, or not printed at all.'''
* Ctrl + letter key shortcuts can be simulated using the appropriate [[ASCII]] Control character codes 1 to 26 shown below:

:''Explanation:'' If the Windows shortcuts are set up properly, printing ASCII Control characters acts like the user selected the control + letter combinations to ''Select all'' (CHR$(1)), ''Copy'' (CHR$(3)) and ''Paste'' (CHR$(22)) the text with the Windows Clipboard. If the editor program's CTRL key combinations are different, use the matching letter [[ASCII]] code from A = 1 to Z = 26 in the text editor.
