As we all know, the Print Screen key is a copy screen key, you can quickly grab the current screen content through the Print Screen key, and then paste it into an image processing program such as "painting" or "Photoshop" for later Processing. However, the following atypical usages may not be very familiar to many friends. Let me introduce you to a few typical usages of the Print Screen button today. You will be surprised when you look at it. I didn’t expect the Print Screen button to work. Use it like this!
1. Enabling high contrast
The effect of high contrast is to increase the screen contrast with an optional color combination, making it easier for users to see the screen. Because high contrast is designed for people with visual impairments, it is not very useful for most users, but if your eyesight is not good, this feature is very useful.
Simultaneously press the Alt and Shift keys on the left side of the keyboard, and without releasing the above two keys, press the "Print Screen" button. At this point, you will hear a "beep" and pop up a "Enable High Contrast" dialog. Click the "OK" button to enable high contrast. In addition, you can also set your favorite high-contrast scheme by clicking the "Settings" button. The specific steps are to first click the "Settings" button in the "Enable High Contrast" dialog box, and in the "Accessibility Options" dialog box that pops up, click the "Settings" button in the "High Contrast" column, as shown in Figure 1. . Then pop up the “High Contrast Settings” dialog box, select a solution you like in the “High Contrast Appearance Scheme” drop-down list box, and click the “OK” button. In addition, you can also make the same settings through the accessibility options of the control panel.
Figure 1 2. Grab the current active window
In general, we press the Print Screen button and the content displayed on the current screen will be captured. However, we usually only need to grab the content in the current active window, so it is very troublesome to perform proper cropping after each capture.
In fact, we can hold down the "Alt" key, press the "Print Screen" take a screen capture, so grab image is just down the contents of the current active window, and then save it.
3. Grab a movie screen
Although it is easy to grab the contents of the current screen with the Print Screen button, there is nothing to do with the video "Print Screen". When we watch a movie, we have a wonderful video screen. When I want to grab it, I find that only the frame of the player is caught. The middle interface will become dark after being saved. The current video is dynamically played along with the player without saving. At this time, we often have to use professional capture software or screen recording software to capture the video images we need. Professional capture software or screen recording software not only takes up a lot of system resources, but not everyone has such a "big chunk" at hand. Is there any way to make "Print Screen" also have the function of grabbing video? Hard work pays off, there are still ways.
"Windows Media Player 9.0": Click "Tools→Options" in the Windows Media Player player menu bar before the screen capture, select the "Performance" tab in the pop-up options dialog box, and drag " The small slider of the Video Acceleration option sets the Video Acceleration from "Full" to "None", as shown in Figure 2, click the "OK" button. Close and restart Windows Media Player, then you can arbitrarily grab videos from Windows Media Player. After the screen capture, forget to set the above "Video Acceleration" to "Complete".

"RealPlayer": Click "View → Preferences" in the RealPlayer player menu bar before the screen capture, select the "Performance" tab in the pop-up "Preferences" dialog box In the "Video Card Compatibility" section, remove the check mark from the "Use Video Optimized Display" check box and click the "OK" button. Close and restart RealPlayer. Also, after the screen capture, don't forget to change the above settings.
"RealOne Player": Click "Tools → Preferences" on the RealOne Player player menu bar before the screen capture, then click "Hardware" in the pop-up window, then in the right pane Locate the "Video Card Compatibility" section and drag the scroll bar to change "Video Card Compatible" to "Reliable", as shown in Figure 3, click the "OK" button.
Figure 3 4. Grab DirectX Graphics
Like the movie capture screen, the Print Screen button usually cannot capture DirectX images, but it doesn't matter. As long as we subtotal, we can give the Print Screen key more. Magical magic, the Print Screen button makes it easy to grab DirectX images.
Click “Start→Run”, enter “Regedit” in the pop-up running dialog box, and press Enter to open the registry editor. In the Registry Editor, expand the following branch: [HKEY_LOCAL_MacHINE\\Software\\Microsoft\\DirectDraw], create a new "DWord" value in the window on the right and rename it to "EnablePrintScreen". Double-click, change its value data to "1" in the pop-up edit dialog box, click the "OK" button, and close the Registry Editor. Now that the Print Screen button already has the ability to grab DirectX images, don't try it!
