## Vimwiki-like link navigation
This snippet allows to navigate next/previous links with Tab/Shift+Tab.
It mimicks the behaviour of vimwiki keybindings where you would press Tab several times to get to the link you want.
Append this function to the file mentioned above (after jumpHeading).
```js
function jumpNextLink(isForward) {
const editor = view.editor;
let posToSearchFrom = editor.getCursor();
posToSearchFrom.line += isForward ? 0 : -1;
const cursorOffset = editor.posToOffset(posToSearchFrom);
const lookupToUse = isForward ? regexIndexOf : regexLastIndexOf;
let headingOffset = lookupToUse(editor.getValue(), /\[\[/g, cursorOffset);
// If not found from the cursor position, try again from the document beginning (or reverse beginning)
if (headingOffset === -1)
headingOffset = lookupToUse(editor.getValue(), /\[\[/g);
const newPos = editor.offsetToPos(headingOffset+2);
editor.setCursor(newPos);
}
```
Then put these lines in vimrc file to set the keybindings. Optionally (as in vimwiki) you can have ENTER bound to follow the link.
```
exmap nextLink jsfile mdHelpers.js {jumpNextLink(true)}
exmap prevLink jsfile mdHelpers.js {jumpNextLink(false)}
nmap <Tab> :nextLink
nmap <S-Tab> :prevLink
exmap followlink obcommand editor:follow-link
nmap <CR> :followlink
```
