This section of the manual explains the function of each element in NetLogo's user interface.
In NetLogo, you have the choice of viewing models found in the Models Library, adding to existing models, or creating your own models. The NetLogo interface was designed to meet all these needs.
The interface can be divided into two main parts: NetLogo menus, and the main NetLogo window. The main window is divided into tabs.
The functions available from the menus in the menubar are listed in the following chart.

Comment /
Uncomment |
Used in the Code tab to add or remove semicolons from code (semicolons are used in NetLogo code to indicate comments). | |
| Shift Left / Shift Right | Used in the Code tab to change the indentation level of code. | |
| Format | Used in the Code tab to correct the indentation of the currently selected code. | |
| Snap to Grid | Available only in the Interface Tab. When enabled new widgets stay on a 5 pixel grid so it is easier to line them up. (Note: this feature is disabled when zoomed in or out.) | |
| Convert from 5.3.1 to 6.0 | Available only in an ".nls" code tab. Treats the code in this tab as though it were written in 5.3.1 and converts it to run in NetLogo 6. Note that this will not take into account code defined in the main code tab. "Undo" doesn't take this operation into account, so you won't want to save unless you're satisfied with the changes. | |
| Tools | ||
| Preferences… | Opens the preferences dialog, where you can customize various NetLogo settings. On a Mac, this item is on the NetLogo menu instead. | |
| Halt | Stops all running code, including buttons and the command center. (Warning: since the code is interrupted in the middle of whatever it was doing, you may get unexpected results if you try to continue running the model without first pressing "setup" to start the model run over.) | |
| Globals Monitor | Displays the values of all global variables. | |
| Turtle Monitor | Displays the values of all of the variables in a particular turtle. You can can also edit the values of the turtle's variables and issue commands to the turtle. (You can also open a turtle monitor via the View; see the View section below.) | |

| Close Monitors for Dead Agents | Closes all open agent monitor windows targeting dead agents. | |

At the top of NetLogo's main window are three tabs labeled "Interface", "Info" and "Code" . Only one tab at a time can be visible, but you can switch between them by clicking on the tabs at the top of the window.
Right below the row of tabs is a toolbar containing a row of controls. The controls available vary from tab to tab.
NetLogo always saves and loads models in the UTF-8 character encoding, which includes a wide range of international characters.
If you are in a locale other than U.S. English, let us know if you have any trouble using your local character set.
The Transition Guide has advice on converting models containing international characters from earlier NetLogo versions.
Most of NetLogo's GUI, and some of its error messages, are now "internationalized". This means that it is now possible to display NetLogo in different languages.
We say "possible" here because the current release of NetLogo only supports English, Spanish, Chinese, Russian, and Japanese.
The work on internationalization is not complete. We are asking for help from the user community in helping us localize items such as the menus and error messages.
By default, NetLogo uses the same language your operating system is set to, if available. (If unavailable, you get English.)
You can record a preference for a different language by changing the "User Interface Language" option in the preferences dialog. Once a new language is chosen you will have to restart NetLogo.
We hope NetLogo will become available in many different languages. If you would like to translate NetLogo to your language, see this wiki page for instructions.
