Note: It is possible to combine multiple command into a single sequence using a semicolon. For example, the following sequence disables line wrapping, enables text selection, and sets background to blue: `\e[12:2;29:1;28:44p` or `\e[12:2;29:1;28:48:2:0:0:255p`.

Note: Since `CSI p` sequences are used by other terminals, all private vt-sequences must be replaced with alternative ones using Lua scripting via APC.
