The Front-End Editor supports various display settings:
Changed lines indicator
This feature allows you to see which parts of the code have been changed during the current session and which have been saved.
Line numbers
This feature helps you to navigate through the code. It also helps you to notice wrapped lines, when you are in word wrap mode.
You can hide or display indicators, changed lines, numbers, and outlining margins depending on the amount of horizontal space available.
Protected areas
This feature allows you to define part of the document as read-only. It displays the area in a different color and an additional symbol appears in the margin.
Current line highlighting
This feature allows you to find the current cursor position in the document.
White space
This feature allows you to see hidden symbols such as spaces, tabs, and line breaks.
Vertical and horizontal scroll bars
You can hide or display both vertical and horizontal scroll bars.
Page Width indicator
This feature allows you to use the page width to check the length of your lines and to see if they are inside a defined range.
Structure separators
This feature allows you to see the end of high-level structures (function, subroutine, class, method and so on). It separates them from one another and facilitates the navigation.
