When using StarChapter's text editor tool, keyboard shortcuts for common tasks are very helpful. These often work more consistently than other options that may vary due to browser differences. Specifically, cut/copy/paste buttons don't work in many browsers due to security limitations, but the keyboard shortcuts for those same actions will work instead.
Cut Control + X
Copy Control + C
Paste with previous formatting Control + V
Paste text-only content and strip previous formatting Control + Shift + V
