Documentation
This documentation is a very early and unfinished version. Please do not rely on any information stated.
Otter is a powerful, still lightweight browser based on Qt5. Its main source of inspiration is the former Opera 12.16 and earlier.
Otter browser can be launched from desktop icon, applications menu or command line. On startup, Otter will display a startpage, homepage or session chooser.
Startpage is a set of desktop icon-like shortcuts to multiple webpages that the user can customise. This is the default startup behaviour.
Homepage is a webpage that the user will have to set so the browser can go there at startup.
Session chooser is a startup dialog to select the specific formerly saved sessions and tabs for launching.
For command line options, type otter-browser -h or man otter-browser in a terminal or console.
The quick preferences menu allows you to quickly enable and disable features like images, javascript, and plugins. Press F12 to access it.
You may not want all settings to apply to all websites at all times. For example, for performance or security reasons you might wish to globally disable Javascript, only to enable it on certain websites. The easiest way to set up site preferences is by right clicking on a page while browsing.
Browser actions can be triggered by keyboard shortcuts. For example the Back action (go back one page in browser history) is usually done by clicking the Back button with the mouse, but it can also be triggered by Alt+← on the keyboard.
A very useful keyboard shortcut is tabs switcher or tabs cycler: Ctrl+Tab and Ctrl+Shift+Tab
In Otter browser, keyboard shortcuts, also known as keybinds, can be assigned and configured to all actions that are implemented in the browser. The configuration dialog is located at Preferences (accessible with the keyboard shortcut Ctrl+F12 by default) → Advanced → Keyboard. There you can select, clone, edit and remove different keyboard profiles.
Mouse gestures are a convenient feature that trigger browser actions by mouse movements instead of pointing and clicking. To use a mouse gesture, hold down the right mouse button, make the movement over the Otter browser window and then release the button. For example, to move a page back in browser history:
- Hold down the right mouse button
- Move the mouse to the left over the Otter browser window
- Release the button
To move a page forward in browser history, move the mouse right in the second step as described. To move up a directory, move the mouse in the second step first upwards, then 90 degrees to the left, and then release the button.
Tabs switcher or tabs cycler is accessible with the following mouse gesture: Press the right mouse button and scroll.
Preconfigured and configurable mouse gestures are found in gestures.ini
