====== Screen Shots ======

You may need to capture what is shown on your screen to share with someone else.

The method for capturing a screen shot varies by operating system.

  * **Windows 10:** You can either use a keystroke, or the Snip & Sketch tool. See this [[https://www.cnet.com/how-to/8-ways-you-can-take-screenshots-in-windows-10/|CNet Page]] for more details.
    * Keystroke
      * Pressing the Print Screen key will copy the current screen to the clipboard, so you can paste the image where you want it.
      * Pressing the Windows key + Print Screen key together will capture the screen and save the image to Pictures -> Screenshots.
      * Pressing Alt + Print Screen together copies the current window to the clipboard.
    * The Snip & Sketch tool can be opened by pressing the Windows key + Shift + S.  For more details on using Snip & Sketch, see this [[https://www.cnet.com/how-to/8-ways-you-can-take-screenshots-in-windows-10/|CNet Page]].
  * **Macintosh:** You can either use a single keystroke, or the Screenshot application.
    * Using a keystroke: (See also [[https://support.apple.com/en-us/HT201361|Apple Support Page]])
      * To capture the entire screen: Press and hold Cmd + Shift + 3 together.  (That is, the  Cmd button, the Shift key, and the number 3).
      * To capture a region: Press Cmd + Shift + 4 together. Your cursor becomes a cross-hair icon. You can click and drag this over the region you want to capture. When you release, the region will be captured.
      * To capture a window: Press Cmd + Shift + 4 + Spacebar.  Your cursor becomes a camera icon.  Click the window you wish to capture.  (It will highlight when you mouse over it.)
    * For more flexibility, including an option to annotate your screenshot afterwards, use "Screenshot" app.  (You can search for it using the Launch Pad, or look for it in Applications -> Utilities.)  See the [[https://support.apple.com/guide/mac-help/take-screenshots-or-screen-recordings-mh26782/mac|Apple Support Page]] for more information.
    * In all cases, the screen shot will save on your desktop with a title "Screen Shot" and the date and time by default.
  * **Linux**
    * You can either use a combination of keystrokes, or a screenshot application.
    * Keystrokes may depend on the version of linux you are using.
      * To capture  the entire screen: Press PrtScr.  This will save a copy of the entire screen to the ~/Pictures directory.
      * To capture a window: Press ALT + PrtScr (unmodified).  This will save a copy of the window under the mouse pointer.
      * To capture a region: Press and hold shift, press and release PrtScr.  This will change the mouse pointer to a + and you can select a region of the screen with the left mouse button.
      * Modifying each of these commands by adding the CTRL key will copy the selected image to the copy buffer.
        * Hold CTRL, Press PrtScr will copy a screen shot of the entire screen to the copy buffer.
        * Hold CTRL, Hold Alt, Press PrtScr will copy the selected window to the copy buffer.
        * Hold CTRL, Hold Shift, Press PrtScr will allow you to select a region of the screen and copy it to the copy buffer.
    * For more flexibility, there are multiple applications available that will allow you to take a screenshot.
