Have you ever wondered what the use of all those F numbered keys on the top of your keyboard are all about? Best known as function keys, they are programmed to perform standard tasks depending on the operating system or application you are using at the time (i.e. PCs with Windows OS vs Mac computers). Functions keys can also be used in combination with other keys such as the ALT, FN, and/or CTRL keys to perform quick actions.
Below is a list of common functions performed using the function keys:
F1: Activates the help window of the current program you are working on for the majority of applications.
F2: If you are using Microsoft Word CTRL + F2 will activate the print preview window. For Windows OS users, clicking F2 will allow you to change the name of a highlighted icon, folder, or File.
F3: Using SHIFT+F3 in Microsoft word will toggle between typing in lower or upper case or it will change the first letter of a word to upper case.
F4: Opens up the address bar in internet Explored and Microsoft Edge Browsers. When using Microsoft Word, F4 will repeat your last action.
