-=====Pad2key=====
-This functionality can help you create a per-game mapping of your controller to keyboard keys, in order to play games from old computers like Apple II, Sinclair or DOS and Windows games that are finicky with their joypad support.
-====Define a new pad2key mapping====
-The first thing to do is to select a game and press ''select'', go to either ''Advanced system configuration'' or ''game options'', and select **Create pad to keyboard configuration**.
-In the first case, it'll create a config system-wide, in the second case, a config specific for the game. **If a game has a config setting for itself, it'll not use the system-wide config at all, so editing the system-wide config will have no effect on the game itself**
-{{ :emulators:pad2key_option.png?nolink&400 |Screenshot of the options screen}}
-Then you will have the option to select keys for each button/axis on your gamepad, both for player 1 and player 2. For each button/direction you click, you will be presented with a virtual keyboard to select the key you want to map to.

-====Configuration file====
-Once your pad2key configuration is done for a specific game, it stays saved as a ''padto.keys'' or ''game_name.keys'' file next to your rom/in your Windows game directory folder. For a system-wide configuration, it'll be saved in ''/userdata/system/configs/evmapy/system-name.keys'', It is a plain JSON file with, for example:
-    {
-    "actions_player1": [
-        {
-            "trigger": [
-                "hotkey",
-                "start"
-            ],
-            "type": "key",
-            "target": [
-                "KEY_LEFTALT",
-                "KEY_F4"
-            ]
-        },
-        {
-            "trigger": "up",
-            "type": "key",
-            "target": "KEY_UP"
-        },
-        {
-            "trigger": "down",
-            "type": "key",
-            "target": "KEY_DOWN"
-        },
-        {
-            "trigger": "a",
-            "type": "key",
-            "target": "KEY_RIGHTSHIFT"
-        }
-      ]
-   }
-Pad2keys config files can be [[:scrape_from|scraped]] off screenscraper.fr, if you have enabled the option for it.
-You can find some examples from the [[:check_for_updates|Content Downloader]] for Windows games like Ri-Li or Super Mario War, both with embedded pad2key config files.
-==== Launching commands with the pad2key ====
-As you saw earlier, the pad2key can be used to simulate keyboard presses, however, it can also be used to launch specific commands, you need to replace the ''"type" : "key"'' to ''"type" : "exec"'', and set the ''"target"'' to the command.
-for exemple:
-<code>
-        {
-            "trigger": [
-                "hotkey",
-                "pageup"
-            ],
-            "type": "exec",
-            "target": "batocera-screenshot"
-        }
-</code>
-can be used to launch the ''batocera-screenshot'' command with the hotkey+L combo, effectively letting you screenshot in systems that don't support a screenshot feature, but that support the pad2key.
