First of all, the yfwd on the previous row: I'm guessing that there was a double yfwd on the previous row. Whenever you work double yarn forwards (yfwd) or (more commonly) yarn overs (yo), on the next row the 2 yo/yfwd loops are alternately knitted and purled. This makes a nice big - and neat - lace hole.
Yes.
"Yfwd" typically stands for "your forward," often used in digital communication to indicate that someone is forwarding a message or content to another person. It can also be an informal shorthand in texting or online chats. The specific meaning can vary depending on the context in which it is used.
In knitting, the term "yfwd" is an abbreviation for "yarn forward." In order to do a yarn forward, simply pull the yarn strand with which you are knitting between the needles to the front of the work, so that it is in the position normally used when preparing to perform a purl stitch. That's all there is to it!
To use the "yfwd" command at the beginning of a row in a text editor like Vim, first, ensure you are in normal mode. Move your cursor to the beginning of the desired row (using the arrow keys or '0' to go to the start of the line). Then, type "yfwd" followed by the text you wish to copy; this will yank (copy) the specified text forward. If you need to specify a number of characters to yank, you can prefix the command with the desired number (e.g., "y5fwd" to yank five characters).
