The Mac cap screen shortcut, also known as Cmd-Shift-5, is a simple yet powerful tool that allows you to take screenshots of your Mac screen with ease. Introduced in MacOS Mojave in 2018, this shortcut has become a staple for many Mac users who need to capture their screen quickly and efficiently.

To use the mac cap screen shortcut, simply press Cmd-Shift-5 on your keyboard. This will bring up a small panel at the bottom of your display with your screen capture options. From here, you can choose to capture your entire screen, a window, or a selection of your screen.

One of the most useful features of the mac cap screen shortcut is its ability to let you reposition the edges of your selection area while keeping the mouse button or touchpad engaged and pressing the Shift key. This allows you to make precise selections without having to release the mouse button or trackpad.

If you need to move the bottom edge of your selection area, simply hold down the Shift key (after dragging to highlight an area but before releasing the mouse button or trackpad). This will lock in each side of the selection area made with the crosshairs, allowing you to move your mouse up or down to position the bottom edge.

Another useful feature of the mac cap screen shortcut is its ability to let you reposition the entire selection area while keeping the shape and size locked. To do this, simply press and hold the spacebar (after dragging to highlight an area but before releasing the mouse button or trackpad). This will lock in the shape and size of the selection area, allowing you to move it around on the screen without changing its dimensions.

When you're ready to take a screenshot, simply release the mouse button or trackpad. The screenshot will be captured and saved to your Mac's desktop.

Overall, the mac cap screen shortcut is a powerful and versatile tool that can help you capture your Mac screen quickly and efficiently. With its ability to let you reposition edges, lock in selection areas, and take precise screenshots, it's no wonder why this shortcut has become so popular among Mac users.
