There are **three accessibility issues** in this snippet:
1. **Save is not keyboard accessible**
```html
<div class="btn" onclick="saveDoc()">Save</div>
```
A clickable `div` is not focusable or operable with Enter/Space by default. Replace it with a native button:
```html
<button type="button" class="btn" onclick="saveDoc()">Save</button>
```
2. **Delete has no accessible name**
```html
<button onclick="deleteDoc()"><svg ...>...</svg></button>
```
Screen-reader users cannot determine what this icon-only button does. Add an accessible label and hide the decorative SVG:
```html
<button type="button" onclick="deleteDoc()" aria-label="Delete document">
<svg aria-hidden="true" viewBox="0 0 24 24">...</svg>
</button>
Show the rest (38 more lines)
```
Also add `aria-hidden="true"` to the Share SVG; its visible “Share” text already names that button.
3. **The help link text is not descriptive**
```html
<a href="/help/editor">Click here</a> to learn about the editor.
```
“Click here” does not identify the destination when users navigate by links. Use descriptive link text:
```html
<a href="/help/editor">Learn about the editor</a>.
```
### Minimally corrected version
```html
<div class="toolbar">
<button type="button" class="btn" onclick="saveDoc()">Save</button>
<button type="button" onclick="deleteDoc()" aria-label="Delete document">
<svg aria-hidden="true" viewBox="0 0 24 24">
<path d="M3 6h18M8 6V4h8v2m-9 0v14h10V6"/>
</svg>
</button>
<button type="button" onclick="share()">
<svg aria-hidden="true" viewBox="0 0 24 24">
<path d="M4 12v8h16v-8M12 3v13M7 8l5-5 5 5"/>
</svg>
Share
</button>
<a href="/help/editor">Learn about the editor</a>.
</div>
```
**Also verify in the rendered page:** visible keyboard focus and sufficient text/icon contrast—the snippet does not include enough CSS to assess those. `type="button"` prevents unintended form submission if these controls are inside a form.
Keep the wrapper as a plain `div` unless you also implement the keyboard behavior expected of an ARIA toolbar; adding `role="toolbar"` alone is not necessary.
