Most orders will include a mix of standard instructions and also specific text only for that particular order. All of it is typed or inserted in the "Body:" field. Just type away - to add a standard instruction to a work order order simply double-click on it (in the instruction list) and it will be added to the end of the body text of your work order.
The entire body text may be spell checked by clicking the spell check button. All or portions of the text may be underlined, made bold, or made italic by highlighting it, then clicking the appropriate format button.
