/java command

add a button at the top of the screen that simulates the F3 menu on minecraft bedrock or add the /java command which would be followed by the keys the player wants to press like /java touch
  F3+g which displays the chunks or /java touch F3+F4 which allows us to change gamemode. I think it would be a very good idea to add this command to minecraft bedrock because java players have advantages over bedrock players. The /java define F3+F4 on ctrl+alt command could set the control+alt keyboard shortcut to the F3+F4 keys of the java version. The /java remove ctrl+alt command removes the control+alt shortcut.
