## How to Add or Change keymaps for Applications
**First it is important to understand how Kinto operates.**
1. It listens for any focus/active window changes
2. It applies the proper keymap based on the programs name.
3. It may monitor your caret/cursor input status, if the app is known to cause shortcut conflicts with wordwise
4. It runs anywhere from 1 to 3 commands to fully remap your computer.
Ok great, we've covered the basics, now what are your options on modifying functionality?
It depends.
Do you want to remap keys using xkb or xbindkeys with xdotool, or something else entirely?
The choice is yours, but I'd recommend xbindkeys with xdotool for anyone that doesn't want to spend the time or learn xkb. I prefer xkb but it completely remaps your keyboard and it could break things if done poorly.
**Firefox - How to Remap using XBindKeys with Xdotool**
1. By default Firefox is mapped with the standard gui based xkb config, and only if no input has focus does it then run xbindkeys to map the Cmd+Left/Right arrow key location to the Back and Forwards functionality you'd expect.
2. The xbindkeys script takes into account the xkb mapping being the base because it is actually remapping Home and End to Back and Forwards as there is no real reason to reload an entire xkb layout.
~/.config/kinto/user_config.json
```
...
{
"name": "firefox",
"run": "setxkbmap -option;xkbcomp -w0 -I$HOME/.xkb ~/.xkb/keymap/kbd.mac.gui $DISPLAY",
"run_onInput": "killall xbindkeys > /dev/null 2>&1",
"run_offInput": "killall xbindkeys > /dev/null 2>&1;xbindkeys -f $HOME/.config/kinto/.firefox-nw",
"symbols": "",
"types": "",
"de": [
2
],
"appnames": [
"Firefox"
]
},
...
```
~/.config/kinto/.firefox-nw (Note additional keymaps can easily be added to this file and I will accept any PR's with keymaps that align with macs)
```
"xdotool key --delay 0 --clearmodifiers Control_L+bracketleft"
// Alt/Cmd + Left
Home + Release
"xdotool key --delay 0 --clearmodifiers Control_L+bracketright"
// Alt/Cmd + Right
End + Release
```
Once you have made your changes you can restart the Kinto service and the changes will take affect.
```
systemctl --user restart keyswap
```
Under normal circumstances this keymap would not have worked well had Firefox not included 2 keymap options for going forwards or back. In the next example, Chrome, you will see how to solve this very same problem but in xkb format and it is the only way to fix it for Chrome due to conflicting with wordwise shortcuts.
Also the choice of xdotool over something like xte (xautomation) was explicit, xdotool allows you to hold down a modifier and continue to repeat the action(s) and xte does not.
**Chrome - How to Remap Using XKB**
This gets to be a little more complicated, but this is what you have to do to accomplish the same on the xkb level.
**Summary**
1. Copy ~/.xkb/keymap/kbd.mac.gui and append the name of the app. (e.g. chrome)
2. Edit ~/.xkb/keymap/kbd.mac.gui.chrome
3. Add new keybindings to ~/.xkb/symbols/mac_gui
4. Only edit types if you absolutely need to add another modifier level (~/.xkb/types/mac_gui)
Understand that as you add or modify the ~/.xkb/symbols/ files that these two groups **symbols[Group1]** and **actions[Group1]** will be following the order of the modifier levels that are configured in the related ~/.xkb/types/mac_gui or mac_term file.
Also you will have to discover the proper xkb names for keys and that they will often follow *two different* labels/names. eg RGHT vs Right ... **replace key \<RGHT\>** vs **symbols[Group1]= [ Right, ...**.
A good place to get the proper names/labels are these two files.
/usr/share/X11/xkb/symbols/us
/usr/share/X11/xkb/symbols/inet
Ok, so here are the detailed instructions.
1. cp ~/.xkb/keymap/kbd.mac.gui ~/.xkb/keymap/kbd.mac.gui.chrome
2. nano ~/.xkb/keymap/kbd.mac.gui.chrome
```
# Change mac_gui(mac_levelssym)
...
xkb_symbols { include "pc+us+us:2+inet(evdev)+ctrl(swap_lwin_lctl)+ctrl(swap_rwin_rctl)+mac_gui(mac_levelssym)" };
...
# To +mac_gui(mac_chrome)
xkb_symbols { include "pc+us+us:2+inet(evdev)+ctrl(swap_lwin_lctl)+ctrl(swap_rwin_rctl)+mac_gui(mac_chrome)" };
...
};
```
3. Add your new "partial xkb_symbols" via nano ~/.xkb/symbols/mac_gui
```
partial xkb_symbols "mac_chrome" {
// Back Button
replace key <LEFT> {
type[Group1]= "ONE_LEVEL_CTRL",
symbols[Group1]= [
Left,
Left,
Left
],
actions[Group1]= [
NoAction(),
RedirectKey(key=<UP>),
RedirectKey(key=<LEFT>,modifiers=Mod1,clearmods=Control)
]
};
// Forwards Button
replace key <RGHT> {
type[Group1]= "ONE_LEVEL_CTRL",
symbols[Group1]= [
Right,
Right,
Right
],
actions[Group1]= [
NoAction(),
RedirectKey(key=<DOWN>),
RedirectKey(key=<RGHT>,modifiers=Mod1,clearmods=Control)
]
};
```
~/.config/kinto/user_config.json
```
{
"name": "chrome",
"run": "setxkbmap -option;xkbcomp -w0 -I$HOME/.xkb ~/.xkb/keymap/kbd.mac.gui.chrome $DISPLAY",
"run_onInput": "xkbcomp -w0 -I$HOME/.xkb ~/.xkb/keymap/kbd.mac.gui $DISPLAY",
"run_offInput": "xkbcomp -w0 -I$HOME/.xkb ~/.xkb/keymap/kbd.mac.gui.chrome $DISPLAY",
"symbols": "",
"types": "",
"de": [
2
],
"appnames": [
"Chromium",
"Chromium-browser",
"Google-chrome"
]
}
```
4. Not making changes to types but it looks like this. It contains 5 levels of modifiers, Base, Alt, Control, Shift+Control, and Shift+Alt. Additional Levels can and may be added later, but please do not change the order of the Levels or existing symbols files will break!! You can add new levels however without issue.
```
default partial xkb_types "addmac_levels" {
type "ONE_LEVEL_CTRL" {
modifiers= Mod1+Control+Shift;
map[Mod1]= Level2;
map[Control]= Level3;
map[Mod1+Control]= Level3;
map[Shift+Control]= Level4;
map[Shift+Mod1] = Level5;
level_name[Level1]= "Base";
level_name[Level2]= "Alt";
level_name[Level3]= "Control";
level_name[Level4]= "Shift with Control";
level_name[Level5] = "Shift Alt";
};
};
```
Once you have made your changes you can restart the Kinto service and the changes will take affect.
```
systemctl --user restart keyswap
```
