ps. not sure what ctrl+alt+tab: real tab in markdown fields this is supposed to do but seems my OS wants to take over and ignore SN specific task

interesting, which browser do you use?

When I press ctrl+alt+tab, I get a tab. A single tab is the same as a code block:

with tab:

test

wrapped in ```

test

but with ctrl+alt+tab, you can indent your code multiple times:

		test

which isn't possible with only tab since that will select the next input (which is the reply button here)
