I have searched high and low for a clear explanation of this, but I can’t find one so I assume it’s so simple that nobody needs it explained.

Except me.

Why is my theme full of code like this

“

I thought _e() was a translation function. What is going on here?

Please excuse my ignorance,

It is a translation function. Wrapping ‘Blog Posts Feed’ in _e() ensures that it appears in the .po file that translators use to create language packs. The ‘buddypress’ argument ensures that it is associated with the ‘buddypress’ textdomain (since potentially the same string might be translated in different ways when part of different software packages).

The difference between __() and _e() is that _e() echoes the string to the screen.

Thanks for that.
And here I was thinking it was just ‘shorthand’ for echo()
