Your MK300 has a row of F-keys above the number keys. The F-keys have two states:

• Normal: F-keys in their normal state can be programmed to perform a variety of tasks. To use F-keys in the normal state, press the F-key you wish to use.

• Alternate: The F-key will send a pre-programmed command (ie. Print) when the FN key (shown below) is pressed simultaneously with the F key.

  

Alternate functions:

The F-keys are pre-programmed with alternate functions shown by the symbol on the F-key. To use these pre-programmed functions, press the FN key and the F-key simultaneously.

These functions can be changed in SetPoint as described in Knowledge Base article 360023222694.
