Excluded URLs and keys | Wholly or partially disable Vimium. "Patterns" are URL regular expressions; additionally, "*" matches any zero or more characters. If "Keys" is left empty, then Vimium is wholly disabled. Otherwise, just the listed keys are disabled (they are passed through).

Scroll step size | The size for basic movements (usually j/k/h/l). px
Characters used for link hints | The characters placed next to each link after typing "f" to enter link-hint mode.
Numbers used for link hints | The numbers placed next to each link after typing "f" to enter link-hint mode.
Miscellaneous options | Use smooth scrolling
| In link-hint mode, this option lets you select a link by typing its text. Use the link's name and numbers for link-hint filtering
| You activate the link with `Enter`, always; so you never accidentally type Vimium commands. Require `Enter` when filtering hints
| Prevent pages from focusing an input on load (e.g. Google, Bing, etc.). Don't let pages steal the focus on load
| When enabled, the HUD will not be displayed in insert mode. Hide the Heads Up Display (HUD) in insert mode
| Switch back to plain find mode by using the `\R` escape sequence. Treat find queries as regular expressions
| This forces the use of `en-US` QWERTY layout and can be helpful for non-Latin keyboards. Ignore keyboard layout
Previous patterns | The "navigate to previous page" command uses these patterns to find the link to follow.
Next patterns | The "navigate to next page" command uses these patterns to find the link to follow.
New tab URL | The page to open with the "create new tab" command. Set this to "`pages/blank.html`" for a blank page (except incognito mode).
Default search engine | The search engine to use in the Vomnibar (e.g.: "https://duckduckgo.com/?q=").
CSS for link hints | The CSS used to style the characters next to each link hint. These styles are used in addition to and take precedence over Vimium's default styles.
