Limits and shortcuts
This page collects the size limits you can run into and the keyboard shortcuts that save you clicks.
Books
| Limit | Value | What you see past it |
|---|---|---|
| File type | EPUB or a PDF with real text | "Lazy Reader reads EPUB and PDF. Convert this book to EPUB with Calibre first." for MOBI and Kindle files |
| File size | 100 MB | "This file is over 100 MB." |
| Shortest book | 1,000 words | "This book has fewer than 1,000 words of text." |
| Longest book | 300,000 words | "This book has more than 300,000 words, which is over the limit." |
| Whole book | 2.4 million characters | "This book has more text than Lazy Reader can read in one go (over 2.4 million characters)." |
| One chapter | 1.8 million characters | "One chapter is more than 1.8 million characters, which is over the limit. Cut it into smaller chapters first." |
| Chapters | 120 | Chapters past the 120th are joined into the last one. |
| Copy protection | None allowed | "This book is copy-protected (DRM). Lazy Reader can only read books without DRM." |
| Scanned PDFs | Not read | "This PDF is scanned images with no text. Lazy Reader cannot read it yet. Use a text PDF or an EPUB." |
Long chapters are summarized in parts, so you do not need to cut them yourself. See Add a book.
Saves and imports
| Limit | Value |
|---|---|
| Text the Chrome clipper sends for one page | About 500,000 bytes. A longer page is cut and the clipper tells you. |

Feed shortcuts
These work on a computer when the window is wide enough to show the feed and the open item side by side. They do nothing while you type in a field or a dialog is open.
| Key | What it does |
|---|---|
j or ↓ | Open the next item in the list. |
k or ↑ | Open the previous item. |
e | Archive the open item. A message with Undo appears. |
/ | Jump to the search field. |
Esc | Leave the search field. |
Review shortcuts
On a computer, with a row open in the panel on the right of Review:
| Key | What it does |
|---|---|
↓ | Open the next row. |
↑ | Open the previous row. |
See File resources and review them.
Other keys in the app
| Where | Key | What it does |
|---|---|---|
| Adding a tag on an item | Enter | Adds the tag. A comma also ends a tag. |
| Adding a tag on an item | Backspace in an empty box | Removes the last tag. |
| Adding a tag on an item | Esc | Closes the box. |
| Edit types, on the drag handle of a type | Alt + ↑ or ↓ | Moves the type up or down the list. |
| Edit types, renaming a type | Enter / Esc | Keeps the new name / puts the old one back. |
Chrome clipper shortcuts
| Mac | Windows and others | What it does |
|---|---|---|
Cmd+Shift+O | Ctrl+Shift+O | Open Lazy Reader Clipper on the current page. |
Alt+Shift+O | Alt+Shift+O | Quick clip: open the clipper and save the page at once. |
To change them, open the clipper's settings, click Shortcuts, then Change in Chrome. That opens chrome://extensions/shortcuts, where Chrome keeps every extension's keys. Chrome may list two more keys for the clipper, Toggle highlighter and Toggle reader. They come from the app the clipper is built on and are not covered here.
