++++
+
+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+T` to open the terminal
+We can join multiple modifiers by simply putting all of them as the mod:
+
+```shell
+Silent Key T      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.
