# Introduction

## Notation Used in This Documentation

The following notation is used in this documentation.

### Menu Notation

Menu names and menu items are shown in bold.

For example, select Open from the File menu.

### Key Binding Notation

Key bindings, or shortcuts, use multiple keys at the same time. Shortcuts show the keys to press with a "+" sign.

For example, CTRL+S directs you to press the s key while holding down the CTRL key.

### TWL Manual Tools Installation Folder

The folder in which TWL Manual Tools is installed is shown as `$(TWL-ManualTools_Root)`.

## Compatibility of Page Files Created on Earlier Versions

### Differences in Appearances of Page Layouts Caused by Compatibility of Page Files (NTPG) and Changes in Non-Breakable Characters

Pages files created on versions of TWL ManualEditor 2.2.0 or earlier can also be loaded to TWL ManualEditor version 3 and later.

However, in order to make manual creation more efficient, non-breaking characters for automatic wrapping were added and a special process for single-byte spaces was added. There may be differences between where automatic wrapping occurs depending on the horizontal width of text objects.

When using TWL ManualEditor version 3 or later, check the line wrap positions of page files created using TWL ManualEditor Version 2.2.0 or earlier.
