# Browse issues
## Unread issues
To quickly display just the unread issues, use the issue's filter function - select `Filter by unread` from the filters at the top of the issue list. Alternatively, you can also display just the unread issues by pressing `U` on your keyboard.
## Read it later
If you want to read it later, there are two ways to do it in Jasper.
The first is to return an issue to unread by selecting `Mark as Unread` from the issue's floating menu. Alternatively, you can press `I` on the keyboard on a selected issue to mark it back as unread.
The second way to bookmark an issue is to add it to your bookmarks. Select `Add to Bookmark` from the issue's floating menu. Alternatively, you may bookmark a selected issue by pressing `B` on the keyboard.
{% tabs %}
{% tab title="Mark as unread" %}
{% endtab %}
{% tab title="Add to bookmark" %}
{% endtab %}
{% endtabs %}
## Exclude unwanted issues
You can use the archive feature to exclude issues that you do not need to view in the future. To archive, select `Move to Archive` from the floating menu. Alternatively, you may archive an issue in the selected state by pressing the `E` key on your keyboard.
## Check unread comments
When viewing an issue in Jasper's built-in browser, Jasper will highlight the comments that have been added or updated since the last time you viewed the issue. You will also see a mini-map of the comments that have been added/updated on the left side of the issue. You can use this comment highlighting and minimap to quickly see which comments have not been read.
{% tabs %}
{% tab title="Highlight comments" %}
{% endtab %}
{% tab title="Comment minimap" %}
{% endtab %}
{% endtabs %}
Also, any updates to the body of the issue will be displayed as a differential.
{% tabs %}
{% tab title="Notice of difference" %}
{% endtab %}
{% tab title="Show the difference" %}
{% endtab %}
{% endtabs %}
