Conventions

This section describes a collection of uniform styles throughout the manual. The conventions used in this manual are as follows:

GUI Conventions

The GUI convention styles are intended to mimic the appearance of the GUI. In general, the objective is to use the non-hover appearance, so a user can visually scan the GUI to find something that looks like the instruction in the manual.

  or
  Settings > Toolbars > Digitizing
  
  
• Tool: Add a Raster Layer

Text or Keyboard Conventions

The manual also includes styles related to text, keyboard commands and coding to indicate different entities, such as classes, or methods. They don't correspond to any actual appearance.

• Name of a File: lakes.shp

  GEOGCS["GCS_North_American_1927",

Platform-specific instructions

GUI sequences and small amounts of text can be formatted inline: Click { File QGIS} > Quit to close QGIS. This indicates that on Linux, Unix and Windows platforms, click the File menu option first, then Quit from the dropdown menu, while on Macintosh OSX platforms, click the QGIS menu option first, then Quit from the dropdown menu. Larger amounts of text may be formatted as a list:

• do this;
• do that;
• do something else.

or as paragraphs.

Do this and this and this. Then do this and this and this and this and this and this and this and this and this.

Do that. Then do that and that and that and that and that and that and that and that and that and that and that and that and that and that and that.

Screenshots that appear throughout the user guide have been created on different platforms; the platform is indicated by the platform-specific icons at the end of the figure caption.
