+# Keep Alive
+### Don't let the PC fall asleep
+---
+Like having a mouse wiggler on for your Key Croc, except with keys! Unlike a regular mouse wiggler, this will constantly press Control - so typing while it is active is not recommended.
+
+The payload was tested on Windows 10. It may be run with seconds specified as a parameter while in SSH (just remove the MATCH).
+
+*Setup*
+1. Connect the Key Croc and place into arming mode
+2. Place `keepalive.txt` in the payloads directory
+3. Change the `TOTAL_SEC` variable to increase time - default is an hour.
+4. Optionally change the MATCH string to a unique passphrase of your choice
+5. Eject the Key Croc safely
+
+The Key Croc is ready for deployment.
+
+*Deploy*
+1. Connect the Key Croc to target in attack configuration 
+2. Type `__staylive` to start the keep awake routine: it will flash yellow while it is active
+
+*What’s up with the name SaintCrossbow?*
+
+Most of it is because it wasn’t taken. Other than that, I’m a big fan of the literary Saint by Leslie Charteris: a vigilante type who very kindly takes on problem people, serves his own justice, and has a great deal of fun doing it. Also, I just can’t help but think that crossbows are cool.
