## use

### As a symbol

The sign is often found in geometry , technical drawing , plans and related areas:

• Identification of a circle - or radius (circular arc) center ( DIN 406 degree-registration in drawings Part 1) - there but typically (in the form of the "+" plus sign , simple cross within the meaning Reticle ) or a centerline cross pulled up to the bow.
• In some applications, such as sectional drawing , the marking of an auxiliary or dimension line with × ––––––– × , then this dimension is referred to with “ × - × ” in text notes
• In the map display, for example: - × - · - × - · - × - for blocked state border , or = × == × == × = for blocked streets (in street maps, for example, in the sense of "not with trailer", or " winter block " for To find pass roads ).

### Mark with a cross

In the German and Anglo-Saxon cultural areas , the little cross or a cross is often used to select from a list (e.g. for elections ): The selected suggestion or list item is "ticked". The expression “tick the box” in the sense of consent is derived from it. Otherwise it is also common to use the tick ✓ to “tick” .

### Hand signals for a signature

Illiterate people can sign official documents with “three crosses” as a hand sign - here there are × -variants next to + -forms. Even today, a signature must be certified in this form (for example: "A signature that is not made with the name signature, but with a simple hand sign - the most famous are three crosses - requires certification by a notary" § 126 dBGB).

### "Ausixen" of text

"Ausixen" dates back to the time of telex and typewriting : the letter X is used to delete invalid text passages. In today's word processing, strikeout is common ( strikethrough text ), analogous to handwritten strikeout of text.

Various scripts follow this, especially since the consortium explicitly refers to the symbol BALLOT BOX WITH X(U + 2612).
