Trouble editing extlinux.conf

[DruWood]

Hi guys! I'm new in this Tiny Core world and I don't remember how to do this.
I was editing the extlinux.conf file in the terminal without GUI (in dCore) when I realized that it didn't save the file. I put "sudo vi extlinux.conf" and typed:

"default dCore
label dCore
kernel /boot/vmlinuzxenial
append initrd=/boot/dCorexenial.gz tce=sda1" (on each line)
But now I don't know how to save and exit the file, because every time I exit it doesn't save. Thanks!

PS: I'm in a Virtualbox VM

Hi DruWood
Welcome to the forum.

When you are done making your changes:
Hit  Esc  to place you back into command mode
Enter  :wq  to save and quit

Thank you!!! You helped me a lot. The problem was that I was writing ":" as having Latin American keyboard, but in the VM I had American keyboard. Thank you very much!
