In Atlantis you can use two typing modes:
Use the Ins key to toggle these modes.
Information about the current typing mode is displayed in the Status Bar.
You can quickly insert ASCII, ANSI, or Unicode symbols to your document that are not directly available through your keyboard. If you know the ASCII, ANSI, or Unicode numeric code of a symbol (either the decimal or hexadecimal code), you can insert it in the following way:
Atlantis will check if the current document font includes the required symbol and insert it.
If the current font does not include that symbol, Atlantis will automatically apply any other appropriate font available on your Windows system.
Tip:
When the Replace selection on input option is on in the "Tools | Options... > Edit" dialog, and the document contains a selection, any new text you type or paste replaces the selection.
When this option is off, a new text is inserted after the selection.
