This function will return true if the key with the particular keycode is pressed, or false if it is not, by checking the hardware directly. It allows for a few more checks, in particular you can use keycodes vk_lshift, vk_lcontrol, vk_lalt, vk_rshift, vk_rcontrol and vk_ralt to check whether the left or right shift, control or alt key is pressed. The function will take a keycode value as returned by the function ord() (only capital letters from A-Z or numbers from 0-9), or any of the vk_* constants listed on the main Keyboard Input page.NOTE: This function is only available for the standard Windows target and the result is independent of which application has focus.

crouch = true;
The above code will check to see if either the left or right alt keys have been pressed, and if they have it sets the variable "crouch" to true.
