This section describes the uniform styles that will be used throughout this manual.

GUI Conventions

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

Platform-specific instructions

GUI sequences and small amounts of text may be formatted inline: Click nix win File osx QGIS ‣ Quit to close QGIS. This indicates that on Linux, Unix and Windows platforms, you should click the File menu first, then Quit, while on macOS platforms, you should click the QGIS menu first, then Quit.

Larger amounts of text may be formatted as a list:

  • nix Do this

  • win Do that

  • osx Or do that

or as paragraphs:

nix osx 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.

win 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.

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