lock icon was clicked. Moving to the last line (with ctrl+end or click)

Also trying to align cases of `getKeyBinding`. Somtimes it returns null and sometimes it returns undefined. Prefer using undefined for all cases

More manual conversion of index based for loops to for-of loops

Replaces many loops of the form:

```js
for (let i = 0; i < elements.length; ++i) {
    const i = elements[i];
   ...
}
```

with:

```js
for (const element of elements) {
    ...
}
```

Mix of a horrible regex based find/replace and manual touch ups

Don't use `Function` as it allows any sort of calling pattern
