Copy and pasting in Firefox
The menu on the right hand mouse button for Copy, Cut and Paste don't work in Firefox, so you need to use keyboard shortcuts.
These are
- Ctrl+A to Select All,
- Ctrl+X to Cut
- Ctrl+C to Copy
- Ctrl+V to Paste.
To paste from Word into Moodle using the Atto Text Editor (Default in Moodle 3.4)
The Atto Editor has a "smart paste" feature which will strip out incompatible formatting codes, so simply copy from your Word or other document and paste into Moodle using the right mouse button menu.
If you need to simplify the formatting, select the text you need to simplify and click the 'Clear formatting' button (see below).

It is always best to do as much formatting as possible in Moodle rather than beforehand in Word or other programs.
