I am a newbie with Slack and the only thing I cannot get to work is opening PDF files from browser. I have to download and then open in file system.
I am using XFCE and my better half likes KDE.
When the dialog box opens to select which program to use to open file, where is file for Adobe Reader? I am stumped.
I know I have to research and read but I cannot find the one single file to do this. Thanks and don't be too rough on me.
