Purchased pattern for making a beret

Unfortunately, not everything in this pattern is clear.
What does the abbreviation “Fm” mean?
I know that “fM” stands for single crochet stitches.

Hello, can I help you? At the beginning of all my patterns, I explain what the abbreviation means.

Thank you for your help.
I have read the abbreviations for the beret and
understood them.
R - row
M - stitch
Lftm - chain stitch
fM - single crochet
Stb - double crochet
Kettm. - slip stitch
RStbv - front post double crochet
RStbh - back post double crochet

So far, everything is clear. But what does "Fm" mean in the instructions,
where it first appears in step 4? "Fm" comes up several times,
1 fM, 2 Fm, Lftm 1, etc.
Unfortunately, I did not understand that.
