什么不将子弹字符添加到富文本框？

为什么他们必须点击图片框？

不能只是是否像Word中的子弹按钮会更新富文本框？

通常，项目符号会应用于选定的文本集。

请澄清！

Wh not add the bullet characters to the rich text box?
Why do they have to click on a picture box?
Couldn't it just be a bullets button like in Word that would update the rich text box?
Usually bullets are applied to a selected set of text.
Please clarify!
