I'm a day in Fvwm, and it's rock solid.
Time to adjust it to my needs
Let's start with keyboard control, as I prefer over using mouse.
We can open `~/.fvwm/config` and make changes.
The default one is _very_ nicely commented, so it's a pleasure to modify.
Then, all we need is to `restart` the wm and we're ready.
By default, you can use `C^F1` - `C^F2` to change active desktop.
The problem is that I don't have F-keys on my keyboard and I want to relegate all WM bindings to `super` key (aka "windows" key).
Ergo, I want `Super^1` to `Super^4`.
First of all, I don't want my `Super` to star terminal - all I needed to do was to comment out
```shell
Silent Key Super_R A A Exec exec $[infostore.terminal]
```
I will reassign it later on.
The [bindings documentation](https://www.fvwm.org/Wiki/Config/Bindings/) inform us that the binding format is
```shell
Key Name Context Modifier Command
```
So, what I want to achieve is
```shell
Silent Key 1 A Super GotoDesk 0 0
```
There is no super as modifier as default, but we can use any `mod` key.
It varies between OSes, so we need to check:
```shell
$ xmodmap #
xmodmap: up to 4 keys per modifier, (keycodes in parentheses):
shift Shift_L (0x32), Shift_R (0x3e)
lock Caps_Lock (0x42)
control Control_L (0x25), Control_R (0x69)
mod1 Alt_L (0x40), Alt_R (0x6c), Alt_L (0xcc), Meta_L (0xcd)
mod2 Num_Lock (0x4d)
mod3 ISO_Level5_Shift (0xcb)
mod4 Super_L (0x85), Super_R (0x86), Super_L (0xce), Hyper_L (0xcf)
mod5 ISO_Level3_Shift (0x5c)
```
Therefore, my `super` keys is `mod4` and the bindings will be
```shell
Silent Key 1 A 4 GotoDesk 0 0
Silent Key 2 A 4 GotoDesk 0 1
Silent Key 3 A 4 GotoDesk 0 2
Silent Key 4 A 4 GotoDesk 0 3
```
Now, back to the terminal.
I want `Super+Shift+Enter` to open the terminal
We can join multiple modifiers by simply putting all of them as the mod:
```shell
Silent Key Return A 4S Exec exec $[infostore.terminal]
```
The terminal command is a variable (`infostore`) because it's used in multiple places.
I'm still using the good, old st, so I modified to
```shell
InfoStoreAdd terminal st
```
I also want to have a quick way to run emacs
```shell
Silent Key E A 4 Exec exec emacs
```
And to mimic MacOS `Ctrl+shift+Q` to close active window
```shell
Silent Key Q A CS Close
```
This makes Fvwm very much usable.
My muscle memory is again in use.
It's still far from where I want it to be, but it's getting there.
