As I write this, many Jews around the world have just concluded their second consecutive Shabbat since the COVID-19 outbreak led to the temporary closures of synagogues. Now that so many of us are davening without a minyan, I thought it would be beneficial to list all of the omissions and modifications that apply in this circumstance.
Some of these are fairly easy: we omit barchu, all kaddishes, and the repetition of the Amidah. Before reciting shema we add the phrase el melech ne'eman. But some are less obvious: for example, when the Torah is not read (because there is no minyan) but one still reads the parsha from a chumash, do we recite Ein Kamocha and the other prayers that precede and conclude the Torah reading? Or do you just go from the end of the Shacharit amidah directly on to musaf? (Actually, I'm pretty sure that's wrong; my siddur says that one omits the second yekum purkan when davening without a minyan, so presumably the first one is read. But what about ashrei, av harachamim, etc.?)
The question, then, is: What is the complete list of omissions and modifications made when davening Shabbat morning without a minyan?
