The word “Code System” at the top of the list represents the root of the “Code System” that you will build from this point. All codes can be created in this way.
In order to create a new code at the highest level, we can do one of three things:
- The easiest option is to click on the New code
symbol in the “Code System” toolbar.
- Another option is to right-click on the Code System row and select New code from the menu that appears.
- The third option is to create a new code by using the keyboard shortcut Alt+N (Windows) or cmd+Alt+N (Mac). For this to work, however, the “Code System” window must be selected.
No matter which way you choose to create a new code, the following window will appear:
Type the name of the new code in the upper dialog field of the window. You can select a color attribute for the new code below. There is an almost unlimited number of colors that you can pick from or design on your own. The dialog field in the lower part of the window enables you to write a code memo, for instance a definition of the characteristics of the new code.
If you select the option Use as default color for new codes, all newly created codes in the project will use the chosen color, e.g. In-vivo codes. Of course you can change this default color each time you create a new code using this dialog.
Creating Subcodes
If you would like to define subcodes, just right-click the parent code and choose the option New code. Again the same dialog window as mentioned above will pop up. If you want the subcode to have the same color attribute as the main code, just click the checkbox “Inherit.”
Creating subcodes can also be completed using the Alt+N (Windows) or cmd+alt+N (Mac) keyboard shortcut or the New code 
icon from the toolbar. It should however be noted that the code for which you wish to create a subcode should be highlighted in blue.
If you have entered text into the memo field of the dialog box, a memo icon is displayed beside the new code in the “Code System” as soon as you close the dialog window.
