There are many people who are new to the right click menus and the options they contain in various Windows programs.
Many people aren't remotely interested in trying to remember all the key combinations necessary to replace the features in a right click. These right clicks are great for everyone who's comfortable with the mouse, but what about the rest of you? The ones who have low vision and love to use the keyboard as much as possible, but still want to complete the same tasks found in these menus. Is there a mouseless solution for you?
Take a look at your keyboard to the right of the space bar and just past the Alt and Windows keys. See it? That key is called the Applications Key and it replaces the right click of the mouse. Many screen readers use this key for totally blind computer users, but you don't have to be a total to get good use of it.
Once pressed, you can use the arrow keys to navigate through the pop up menus and the Enter key to select your choices. If you hit this key accidentally or just want to back out of the pop up menu, hit the Esc key.
Here's a quick note: When I checked my laptop keyboard, I found this key in the top section of the keyboard. You may have to do some searching to find it.
