Tinker's procast consists of a combination of three abilities: Rocket missle, Shivas Guard and Blink. To use it, you need to choose a Tinker hero and reach level 18. The hero must be activated to use the procast.
The following buttons are used to perform the procast:
- Blink (moving a short distance) is assigned to the SPACE key;
- Shivas Guard (activates the protective field of Shiva) is assigned to the TAB key;
- Rocket missle (rocket) is assigned to the W key;
- Rearm (ability recharge) is assigned to the R key.

It should be noted that procast does not require the use of mouse buttons (PCM or LCM). The entire sequence of actions is automated by the script. Instead of performing each action manually, the script will do everything on its own.

Example of using procast:
1. Press the SPACE key to activate Blink and move a short distance to the target.
2. Then press TAB to activate Shivas Guard and create a protective field around yourself.
3. Press the W key to launch a rocket (Rocket missle) at the target.
4. Finally, press the R key to perform Rearm and recharge abilities.

Thus, you will be able to perform effective procast on Tinker using the specified keyboard shortcuts. Don't forget to adjust the keys to your liking in the Keyran program.
