Overleaf starts to retire the "legacy" mode of their online editor.

Fixed `:log` and `:history` (2022-05-12)
* `:log` toggles the log, and
* `:history` summons the history view. Since Ace editor is not loaded in the History view, one needs to click again on the History icon to return to the editor interface.

Mainly, restore the mapping: `;lv`.

* Updated the JumpToPdf command as "synctex-control-goto-pdf" has been updated to be "synctex-control" ==> then, this thing repeats for 4 times.
* Af of 2022-05-12, "fa-arrow-right" is the unique element on the page under the right-arrow.

Update the TogglePDF with new identifier.

Take down the jquery requirement - it breaks the vertical divider for Overleaf

```
// @require https://cdn.bootcss.com/jquery/2.2.4/jquery.min.js
```

It is unclear where this line came from. Likely, from an old version of the Overleaf's ACE editor page: https://www.overleaf.com/learn/how-to/How_can_I_define_custom_Vim_macros_in_a_vimrc_file_on_Overleaf%3F

Add `ESC` as the key to escape from the Writefull suggestion card.

Redo the shortcuts used for jumping to the typos. There is an unknown problem with `[s` and `]s`, which sends the "focus" of the keyboard to some hidden element, where:
* `0` and `-` are mapped to zoom in and out, and
* Visually, some Overleaf element should get boxed in a glowing red box.

Add Writefull support, with
* `]s` and `[s` for jumping to the next/previous spell-checking suggestion, and
* And, `1`, `2`, `3` for selecting over the options offered in the suggestion card.

Use `:o` to toggle the "Symbol Palette" twice.

And, work-in-progress for the spell-checker piece.

Asked for g$ and g0, and Harutyun delivered! The original post is here: https://groups.google.com/g/ace-discuss/c/2hwMMzBbYH8/m/Q0l9vJAqBQAJ?utm_medium=email&utm_source=footer

Further, in normal mode, 0 is mapped to work as g0, and $ is mapped to work as g$.
