Moving the cursor during multi-line editing will revert to single-line editing.
When I use Alt + Left Click to enter multi-line editing, moving the cursor left or right it to become single-line editing.
当我使用 Alt+左键 进入多行编辑后，左右移动光标会变成单行编辑。
Using Ctrl + Left Click to enter multi-line editing, moving the cursor left or right is not an issue.
使用 Ctrl+左键 进入多行编辑，左右移动光标都不会出现问题。
If I use Alt + Left Click to enter multi-line editing, and then use Ctrl + Left Click, moving the cursor is also not an issue.
如果我使用 Alt+左键 进入多行编辑，然后再使用 Ctrl+左键，移动光标也没有问题。
I hope that after entering multi-line editing with Alt + Left Click, moving left or right does not exit multi-line editing. 我希望通过 Alt+左键 进入多行编辑后，左右移动光标不会退出多行编辑。
Same as SciTE, Alt + Left Click creates rectangular selection.
I don't understand what it means. Is this a bug, or a feature? Or is this a Scintilla issue?
