Just for my own personal reference. Here's a quick list of the different types of variables in Modx.
- [(varName)] = site setting, set site wide
- [*varName*] = content or template var
- [*#content*] = content var, like before sets in the document edit screen but the hash allows Quickedit
- {{chunkName}} = chunk
- [[snippetName]] = cachable code snippet
- [!snippetName!] = uncached code snippet
- [+placeholderName+] = place holder used inside snippet templates such as Ditto to show page id or Page title. Need to double chk what the specific snippet supports
