Function of the ctrl key on the computer keyboard

The Ctrl key on the computer keyboard has many functions.

It is also a combination key, which can be used with other keys at the same time to have multiple functions.

However, it also has many functions when used alone with the mouse.

described as follows:

First type: [Copy Object] Drag an object with the mouse on the same disk by default to move the object,

When you hold down the ctrl key and drag, it becomes a copied object.

This function is very convenient when copying files within folders, copying folders between disks, copying pictures in PPT and other objects.

Second type: [Select objects] When selecting objects out of order in an open folder or disk,

You can hold down the ctrl key and use the mouse to select the objects you want to select.

You can also select all objects and then hold down the ctrl key and click on the objects to deselect them.

Third method: [Convert curve to straight line] When using "Curve" in "Shape" to draw graphics in PPT,

Hold down the ctrl key and the curve will turn into a straight line. Release the ctrl key and the straight line will return to a curve. Use this function of ctrl to use curves and straight lines alternately when using "curve" drawing in PPT.

The fourth method: [Fix the center position of the shape] When inserting a shape in PPT,

Hold down the ctrl key, select a fixed point with the mouse and drag it to draw a shape centered on the selected point.

The fifth method: [Adjust page display ratio],

Hold down the ctrl key and scroll the mouse wheel,

You can adjust the display ratio of the page in the open window.

The sixth type: [key combination], the ctrl key has many functions in combination with other keys,

Extended information:

Solution to the problem that the ctrl key cannot switch the input method

1. In win8 or win10, ctrl shift is often no longer effective. At this time, you can switch the input method by selecting the correct shortcut key.

2. Press the "windows logo key + space" to switch the input method once.

3. Long press the "windows logo key" and then press the space. You will find that your input method will be displayed. If you press the space again (of course, the windows logo key remains pressed and does not let go), You will switch to the next input method. You can use this operation to continuously switch input methods.
