* JUMP KEY
*

---

* This plugin mostly uses default RPGMaker MV controls for the jump key
* setup. It also allows use of other keyboard keys but whatever key you
* choose, I advise you to test it isn't conflicting with another control.
*

---

* Possible keys to use for "Key" setting:
* tab
* enter // Not recommended as key already used
* shift // Not recommended as key already used
* ctrl
* alt
* space // Not recommended as key already used
* 0-9
* a-z // Q,W,Z,X are not recommended as they are used
* semi-colon
* comma
* period
* single quote
* pageup
* pagedown
*
* Use one of the below key codes instead for compatibility with gamepads
* ok // A
* cancel // B
* shift // X
* menu // Y
* pageup // LB
* pagedown // RB
* up // D-pad up
* down // D-pad down
* left // D-pad left
* right // D-pad right

*
*

---

* EVENT COMMENT
*

---

* An event can be used to control where the player can and cannot jump. If
* the very first event command of an event's page is a comment with:
* <blockJump>
* Then the player cannot jump over it. Switch the event page to one without
* this comment and then the player can jump over it.
*

---

* REGIONS
*

---

* Region ID's can be set in the settings. The player can not jump over these
* regions. Separate multiple region ID's with commas.
*

---

* PLUGIN COMMANDS
*

---

* JUMPACTION STATUS // STATUS can be TRUE or FALSE to enable/disable
* // the player's jump key.
* Example:
* JUMPACTION FALSE // Disables the jump action key
* JUMPACTION TRUE // Enables it again
*
