What is a placeholder?
A placeholder is a single character, such as an underscore (_) or hyphen (-), that stands in for an unknown or a value that has yet to be filled in. It is used to make sure the layout and structure of text remains the same while content is added, removed, or changes. Placeholders are often used in coding or programming to denote something that will be filled in later when more information is available.
How do I use a placeholder?
Placeholders can be used anywhere you would like to reserve space for something to be added later. Common examples include in databases, documents, spreadsheets and forms where content may change or where information is missing. They are also commonly used in programming languages when elements of code are not yet ready to be defined.
How do I type a placeholder?
To type most common placeholders such as underscores and hyphens on Windows systems, hold down the “Shift” key then press the “minus” key which will create an underscore(_). The “minus” key can also be used on its own (without holding down shift) to create a hyphen(-). For otherplaceholders such as asterisks (*) or carets (^) please refer to your system manual for specific instructions.
In which cases should I consider using placeholders?
Placeholders should typically be used whenever there is incomplete data or if you plan for changes to occur at some point during your work process.
