Gmail – Keyboard shortcut for indenting bulleted list in Gmail message editor with Mac

How to indent a bulleted list in Gmail message editor with Mac, Chrome & Finnish keyboard?

Bulleted list can be toggled with Shift+⌘+8 -> Works OK.

Gmail editor's button has tooltip with shortcuts ⌘+[ (indent) ⌘+] (de-indent). However, I haven't been able to succesfully do that since in Mac Chrome those shortcuts are mapped for for History -> Back & History -> Forward

Something I've tried:

• Plain [ & ] can be entered with Alt+7 & Alt+8 on my keyboard
• ⌘+[ & ⌘+]: History -> Back & History -> Forward
• Alt+⌘+7 / Alt+⌘+8 : Nothing
• Shift+Alt+⌘+7 / Shift+Alt+⌘+7 : Selects previous/next tab
• ⌘+7 : Changes to 7th tab
• ⌘+/ (in Finnish keyboard ⌘+Shift7) : Opens "Help" menu at Mac menu bar.

Not so crucial but would speed up email writing every now and then.
