#include <Inet.au3>
HotKeySet("^+{BACKSPACE}" , "SendUSD") 
#HotKeySet("{F10}", "qui") 

while(1)
sleep(100)
wend

func SendUSD()
$aRes="1234567890"
#sgBox(0,"",$aRes[0])
Send($aRes);
endfunc

func qui()
exit
endfunc

Script start after pressed Ctrl+Shift+Backspace and inserted only if i quickly release the buttons Ctrl and Shift keys but after the program leaves the Ctrl  key stuck 

What is the reason for this and how to solve it?

@selevo we have a pretty great Wiki, which we suggest people (especially new) read before posting. A lot of these commonly asked questions are answered in the FAQ section:
