Standar Control:

The standard control for browser games will vary depending on the game you are playing. However, most browser games use the keyboard and mouse as the primary means of input. Here are some common controls that you may encounter while playing browser games:
• Keyboard: The arrow keys or WASD keys are commonly used to move the character or navigate menus. The space bar is often used to jump, and the Enter key is used to start or pause the game.
• Mouse: The mouse is used to aim and shoot in FPS games, to select options in menus, and to interact with objects in the game. The left mouse button is often used to select or shoot, and the right mouse button is used for secondary actions such as aiming down sights or interacting with objects.
• Spacebar: It's mostly used to jump, shoot or interact with objects.
• Esc button: It's mostly used to pause the game or access the game menu.
• Tab button: It's mostly used to access the scoreboard or inventory.
• The number keys: They are mostly used to switch weapons or select items.
• Ctrl or Shift: They are mostly used for crouching or running.
Keep in mind that different games may have different control schemes, so it's always a good idea to check the game's instruction or tutorial before you start playing.
