I want to delete all instances of the text:

,Reading,2013-03-20,I Speak clap


the dates vary, the beginning and end do not




don't know how to use wildcards and all of that

hi ertu,

Try an ordinary Find/Replace, where:
Find = ,Reading,^#^#^#^#-^#^#-^#^#,I Speak clap
Replace = nothing

Or:

Try a wildcard Find/Replace, where:
Find = ,Reading,[0-9]{4}-[0-9]{2}-[0-9]{2},I Speak clap
Replace = nothing
