PrintScreen key knows how much

is known. The Print Screen key is a copy screen key. The Print Screen key can quickly capture the current screen content and then paste it into an image processing program such as "painting" or Photoshop. save. However, the following atypical usages may not be very familiar to many friends. Let me introduce you to you today. After watching it, you will be shocked. I didn't expect the Print Screen button to be used like this!

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 may not be very useful for our average users, but if your eyesight is not good, this feature is very useful.

Simultaneously press the ALT key and SHIFT key on the left side of the keyboard, and without releasing the above two keys, click the "Print Screen" button. At this point, you will hear a "beep" sound, and a "Enable High Contrast" dialog box will pop up, as shown in Figure 1. 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, pop up the "Accessibility Options" dialog box, and then click the "Settings" button in the "High Contrast" column, as shown in Figure 2. The High Contrast Settings dialog box is displayed. Select a scheme you like in the High Contrast Appearance drop-down list box, as shown in Figure 3. Click the OK button. Figure 4 shows the task manager (Figure 4) after I enabled high contrast. You can see if a big change has occurred since high contrast is enabled.

Alternatively, you can also use the accessibility options of the control panel The same settings.

Grab the current active window

Normally we press the Print Screen button and the content displayed on the current screen will be captured. But usually, we often only need the content in the current active window. It is very troublesome to make proper cutting after each drawing.

Try now, while holding down the "Alt" button, click on "Print Screen" to capture the screen, so that the captured image is only the content of the current active window, and then save.

Grab the movie screen

Although the Print Screen button can be used to easily capture the contents of the current screen, but the video content "Print Screen" can not do anything, when we are watching movies When I had a wonderful video screen and wanted to grab it, I found that only the frame of the player was captured. The middle playback 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, the method is still there:

"Windows Media Player": Click "Tools--> Options" in the WMP player menu bar before the screen capture, in the pop-up options dialog box On the Performance tab, drag the Video Acceleration option's small slider to set Video Acceleration from Full to None, as shown in Figure 5, and click the OK button. Close and restart WMP, well, now you can grab the video in WMP arbitrarily. Remind, after the screen capture, don't forget to set the above "video acceleration" to "complete".
Figure 5
"RealPlayer": Click "View --> Preferences" in the RealPlayer player menu bar before the screen capture, click the "Performance" tab in the pop-up "Preferences" dialog box, In the "Video Card Compatibility" selection, remove the checkmark in front of the "Use Video Optimized Display" check box, as shown in Figure 6, click the "OK" button. Close and restart RealPlayer. Also, after the screen capture, don't forget to change the above settings.

Figure VI
"Realone Player": Click Realone Player Player menu bar in front of a screen capture "Tools - & gt; Preferences" and then in the pop-up window, click the "hardware", then In the right pane, find the "Video Card Compatibility" section and drag the scroll bar to change "Video Card Compatible" to "Reliable" and click the "OK" button.

Grab the DirectX diagram

Like the capture of the movie screen, the Print Screen button is usually unable to capture the DirectX diagram, but it does not matter, as long as we apply a subtotal, you can Give the Print Screen key more magical power, so the Print Screen key can easily grab DirectX images.

Click "Start-->Run", enter "Regedit" in the pop-up dialog box, press Enter to open the Registry Editor. In the Registry Editor, expand the following branch: HKEY_LOCAL_MacHINE\\Software\\Mi-

crosoft\\DirectDraw, create a new "DWord" value in the right window and rename it "EnablePrintScreen". Double-click, in the edit dialog box that pops up, change its value data to "1", 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...
