You can set a sprint delay in the settings menu of the pedometer, which will allow you to run for a certain amount of time without sprinting. To bind a hotkey, hold down a number key while viewing the inventory and click on the item you want to bind. To stop sprinting, press the hotkey again. To start sprinting, press the sprint hotkey and then move forward.
Without NVSE: In NoNVSE mode, you must bind the Vault-Tek Pedometer in your inventory to a hotkey. OR- If you would like to preserve the functionality of the run key, you can set a custom keybinding from the control settings menu of the pedometer. With NVSE: The sprint key replaces the run key. Now you can run freely around the wastes like you've always wanted to, limited only by your action points.
