relative name of object to be checked for. the \$0 of the parent will be automatically added (with a slash). perform a check and output the result 0: not found 1: found to be used only directly inside an abstraction that is to be found directly in a help-patch. find whether a certain part of the doc exists so far, in the current help-patch. uplevel from [doc_exist] to help-patch. this is 1 if [doc_exist] is directly in the help-patch, 2 if it is directly inside [doc_h], etc. does inlet 1 have a doc item ? what about inlet 2 ? this silly name mangling should be abolished. it's 0b=bang, 0f=float, 0g=grid, 0s=symbol, 1p=pointer, 2l=list, ~a=, all other selectors left unchanged. the purpose of this mangling is to enforce a sorting-order. outlet 0 exists outlet 1 doesn't in inlet 0, method bang exists ... but method float doesn't this is one more than the uplevel you'd use for a [gf/canvas_dollarzero].
