# Browser Layer The browser layer is an application layer that uses browser shortcuts such as creating, removing and navigating through tabs and windows. For a browser, I use chrome but most other browsers have similar shortcuts. {% embed url="" %} ### Vimium Extension {% embed url="" %} Vimium is a browser extension that allows links to be clicked on easily without a mouse. This is done by vimuim highlighting 2 letters showing available links and then the user types the 2 letters next to the link to open in a tab or new tab. There are also some other nice features such as being able to searching through tabs or easily going to last tab. One think I dislike about vimuim is that it is alway active and sometimes has weird interactions with text input fields. For this reason, I like to place vimium on a layer and add to other chrome shortcuts. I do this by creating a custom key map in the Vimium extension in the vimium help section, activated by "?" by default. I unmap all shortcuts then add the ones I use. the \ stands for control + letter which I do to avoid conflicts such as youtube's hotkeys that have no modifiers and cannot be easily changed.
![](/files/QFBGPwfaysjsh42TYERp) I then use karabiner elements to map an application layer(hyper keys), to a browser layer that only triggers when chrome is the front most application. So hyper keys remapped into the vimuim keybindings like control + a letter. At the end I show the karabiner code since its quite lengthy. ![](/files/XNuecbLypH8rEQ01b1nz) The full table showing the key mapping is below with an image of the application layer below. |
