# URL Schemes

Soulver implements the x-callback-url specification, allowing you to trigger calculations via URLs.

### To open a specific sheet

To generate a URL to open a specific sheet, control/right-click on the sheet in the sidebar and choose `Copy Local Link to Open Sheet`.

![](/files/-MjEYTqvko-fkEYRd7zr)

The URL has the following form

`x-soulver://x-callback-url/open?&id=23C644E9-1A57-4BC9-AF0E-1787ACDDBE0E`

### To create a new document and evaluate an expression

`x-soulver://x-callback-url/create?&expression=1+1`

### To evaluate an expression and put the result onto the clipboard

`x-soulver://x-callback-url/calculate?&expression=1+1&to_clipboard=true`

### To append an expression to a specific sheet

`x-soulver://x-callback-url/append-line?&id=FD4A6E87-A74A-4BCF-94CE-AEAE4134AC5D&expression=1+1`
