-__"if search string"__ is the string it looks for to decide whether it needs to add the tweak or not, so generally something to indicate the tweak already exists. __"cmdline match string"__ behaves somewhat like this while also being the new cmdline addition for the _patch_cmdline_ function.
+__"if search string"__ is the string it looks for to decide whether it needs to add the tweak or not, so generally something to indicate the tweak already exists. __"cmdline match string"__ behaves somewhat like this while also being the new cmdline addition for the _patch_cmdline_ function. __"prop name"__ also serves as a match check for a property in the given prop file, but is only the prop name as the prop value is specified separately.
 
 Similarly, __"line match string"__ and __"line replace string"__ are the search strings that locate where the modification needs to be made for those commands, __"begin search string"__ and __"end search string"__ are both required to select the first and last lines of the script block to be replaced for _replace_section_, and __"mount match name"__ and __"fs match type"__ are both required to narrow the _patch_fstab_ command down to the correct entry.
