I recently started working at a job that uses macs. When I used to save as in a program in Windows I could name it, tab to file format, for example push j to select jpeg. then save.
On the Mac software I have to select the drop down with my mouse then chose the format I would like to save.
I like to use key shortcuts as much as possible to save time. It seems like it wouldn't be a big deal to pick up the mouse to save in a .png or jpeg format but it kind of drives me nuts. So if there is a way to switch file formats without using a mouse that would be great!
Also, I've tried to just type the extension it for example "fav_16.png" and then it saves "fav_16.png.psd"
