The middle School mathematics class uses the vector symbol, as shown in Figure 1 right effect.
Figure 1
Colleagues have a deep headache with this symbol when editing papers and lesson plans. In fact, in the WPS 2010 Text Tool, we can easily input vector symbols using field codes. Relative to the use of Formula Editor to complete the input, with the field code input can be as normal text to set the font size, font, color and so on.
One, the type of input single character
First press the "CTRL+F9" key to create a space, in which the input code "EQ O (sup8 (→), a)", and then press the "SHIFT+F9" key combination can see the effect. Note that field symbols (curly braces) cannot be entered manually, and field codes should be entered in the English half-width state.
The field code here means that the single arrowhead character is moved up by 8 pixels and the position of the character "a" is overlapped. Is it possible to get the symbol of a vector?
Second, the type of two-character input
The same as the previous entry method, except that the field code is "EQ O (sup8 (→), AB)". After "AB" added a half corner space, is to make the final effect more beautiful. We also need to increase the length of the single arrowhead as compared to the character type. Select the arrow symbol, click menu command "format → font", click the "Character spacing" tab in the Open dialog box, and set to "150%" in the Zoom box, as shown in Figure 2.
Figure 2
If we click the "position" Drop-down list in this dialog box, and select "Up" and then enter the appropriate number in the Value input box, and then move the arrows directly up, then the field code can be simplified to eq o (→,ab) and the effect is the same. As shown in Figure 3.
