ZZ Command
Marks a block of lines so you can refer to them in any command.
ZZ [ line [ / line ] | OFF ]
ZZ [ [ string range ] | OFF ]
(Q=no display)
(Default: * becomes start or end of block)
ZZ line/line marks a range of lines, while ZZ line marks the start or end of a range. ZZ marks one range only, not a rangelist. To mark a single line, say 5, use zz 5/5.
ZZ OFF cancels the currently marked range, eliminating the half-bright display enhancement in Visual.
Examples
/zz 5/10
/change "prog"program" zz
/find "procedure open" (up)
/zz {mark start of block}
/find "@end;~{open}@" (pattern up)
/zz {mark end of block}
/keep savefile zz {save block in a file}
/verify zz {check current range}
/zz off {cancel current range}Notes
The marked range is adjusted for Renum operations. Use Verify ZZ or List ZZ to check the currently marked range. ZZ is also valid as a cut-and-paste operator in Visual mode.
Using a string range on a Find command automatically updates the ZZ marker. For example:
/v zz
ZZ OFF
/find "start"/"end" [
Lines 5/11 saved in ZZ
/v zz
ZZ 5/11
