I am using Lubuntu 18.04.
When clicking right on a file the context menu of the file manager opens up. The file manager is PCmanFM, a great tool. I would like to remove programs from the list of suggested programs to open a certain file with.
For example a text file can be opened with Leafpad and with AbiWord in the default installation of Lubuntu 18, already.
I understand that the entries result from several ways of adding them. Adding such an entry seems to be easier then removing one.
Is there a documentation of the several ways on how to remove entries in context menu of PCmanFM?
