Choose the desired type of hyphen here. The offered hyphens are basically used as described hereafter:
This is a long hyphen (Em-dash) which should basically be used only to visualize a filled in thought in a text.
Example:
iCalamus is a fantastic DTP app—besides that you can use it
for other purposes too—and offers many options.
This hyphen has En-width and will be used basically as a 'Minus', and as a 'from–to' hyphen, etc.
If you want a word to be hyphened by iCalamus without creating and showing a hyphen, use this soft hyphen. Use it to hyphen phrases with special characters (e.g. the & sign like in 'black&white') without entering an additional hyphen which would mix up the phrase. The control character itself will never be shown, it is only recognized by the text formatting.
This hyphen looks like a basic hyphen, but it will never be recognized in text flow. That means if you want phrases like 'T-Online' to be protected against hyphenation, use the nonbreaking hyphen.
