Smart Clips

Smart clips are clips you create manually instead of being imported from copied text. They can also use some very powerful special functions embedded in the text. For example, if you have the smart clip **The quick {clip:1} fox.** and the first copied clip is currently **blue**, then using the smart clip will paste The quick blue fox.

{clip:N} will paste the copied clip that is at the position N indicated by the number.

{date:M/d/yy} will paste the current date and time using the same formatting as the Paste Date and Paste Time commands. You can also use **|+** and **|-** like in those commands.

{ask:Which name?} will prompt you with the text Which name? to enter text that will appear in place of that function.

{pick:this|that|other} will prompt you to choose between this, that or other and then that will appear in place of that function. This prompt will also let you type in any text in addition to choosing from the list.

{random:this|that|other} will randomly choose between this, that or other and then that will appear in place of that function.

{selection} will use the text currently selected at that point in the Smart Clip. If no text is selected it will use the contents of the clipboard instead
