Open Settings (click on cog icon – top right) ❯ See all settings ❯ ‘General’ tab ❯ Scroll through and set the top options as preferred. Grammar, Spelling, Autocorrect and Smartcompose are useful. Keyboard shortcuts ON will avoid hand pain from over use of the mouse – the letter ‘C’ alone will open a new email (Compose) and Ctrl/Command + Enter will send it. Scroll down to bottom and click ‘Save Changes’
