For example, if you want to bring up the Pd manual, look under Manuals/Pd. After failing to find it there look under Pure Data/1.manual/ To find [dist~] you would look in the library "crebs", which stands for "Classes arRanged Erratically By neceSsity", or at your leisure, first search all the other categories where [dist~] is not located. > 2) Use the resources on puredata.info > 3) Manually explore the /extra or /extern folder in your pd install > 4) ++ more ++ I have a search plugin that works with 0.43 (attached).
