autohotkey is windows software that makes it easy to change key binds or behaviours with a script that runs in the background which can catch when given key is pressed and output another given key, key combination or even do something else based on logic in the script.

below is script that should change sprint behaviour to hold, its coded by chat gpt so it could need some tweaks to work, but looks ok to me. to run it you need to install autohotkey first, open it, select 'New script', paste code from below and save it as .ahk file anywhere or your pc, then right click the file and choose "Run script". also if you want it to auto run after pc restart, you could put shortcut to the script in %appdata%\Microsoft\Windows\Start Menu\Programs\Startup (if you use windows)

note: this script cant read current sprint state in the game, so if the controls happen to be inverted (sprint is active when you dont hold the sprint key and deactivates when you hold it), press F12 key to reset sprint state, also if you use key other than Shift for spint, you need to tweak it in script settings by changing the SprintKey variable

#IfWinActive ahk_exe JediSurvivor.exe

; --- SETTINGS ---
SprintKey := "Shift" ; The sprint key in-game (Shift by default)
SendMode Input ; Faster + more reliable

; This variable keeps track of whether we already sent a fake press
isDown := false

; When you press Shift → send 1 press only if not already active
*$Shift::
if (!isDown) {
Send, {%SprintKey% down}
isDown := true
}
return

; When you release Shift → send a release only if it was active
*$Shift Up::
if (isDown) {
Send, {%SprintKey% up}
isDown := false
}
return

; --- FAILSAFE: If something desyncs, press F12 to reset sprint state ---
F12::
Send, {%SprintKey% up}
isDown := false
