Environment, ahead of thought

Disclaimer
It is assumed that you have been working as admin / devops for about five years and are able to find answers in Google. My task is to ask the right questions. Implementation examples will be given for Windows. I offer alternatives for * nix-shaped systems to readers as homework.
Login

Implementation : Install PuTTY . Generate and put your .ppk in the Start-up folder. Pageant will do the rest.
Fast access

Implementation : Launchy (freeware) + PuTTY plugin . I hang on Alt + Space . In addition to an excellent search for files and commands, it allows you to search for Pageant sessions, guessing the names by several letters. Suppose if you have sessions:
- Client1_Host1
- Client1_Host2
- Client2_Host1
- Client2_Host2
all you have to do is enter “c2h1” to get to Client1_Host2 (in this artificial case even just “21” is enough). You can even enter “c1” and select the desired car from three - Launchy will remember your choice and will not ask questions next time.
Window manager

Implementation : Plumb(for personal use). Automatically arranges windows according to the grid you specify. My screen is divided into 5 parts - on the left, a full third of the screen is allocated to the most active window, the rest is 2x2 divided by other background tasks (tail -f, watch -d, mtr). I don’t need to drag new windows from place to place with my mouse, freeing up space among other windows - the last 5 active windows on my screen.
What does this give us?
Now consider a fictional situation from real life in which all the bonuses of this system will become clear. You read Habr, a colleague-programmer approaches you and asks: “Pasha, Client1 on the first host has already completed that very long request, which I composed without the slightest knowledge of the internal architecture of the database, carefully ignoring indexes and using the most poorly optimized operators?”
You put your fingers on the keyboard and give the first chord: Alt-Space c1h1 ENTER. I bet people don’t even notice what happened. You just touched the keys, and at the same second the window with Habr was pushed to the side, and its place was taken by the open terminal Client1_Host1. For a person who is accustomed all his life at best to search for the desired tab in a long list of open sessions, this will already look like magic.
In the terminal, you do something like “pgrep -af long_query”, you see that the process is still hanging and press Ctrl-D. The window closes, and the Habr (previous active window) returns to its place. You don’t need to minimize the terminal, thinking that you will still be working with this host - you know that opening a new one is faster than looking for the old Alt-Tab or mouse aiming in the taskbar.
After 2 minutes, a colleague returns with the same question. This time you will be faster than the train station. Watch your hands. Alt-Space ENTER UP ENTER Ctrl-D . What was it - Fatality? Launchy remembers your last command, you don’t even have to look at his window. They opened the terminal, called the previous command in the shell, saw a non-zero result and closed the window.
Here he comes for the third time, and to get rid of him, you run “watch -d !!” in the freshly opened terminal and drag the window to the corner. Habr again occupies the main part of the desktop, and watch in a small window will highlight you changes in the list of processes when a long query to the database ends.
This is only one part of the doctrine of the Quick Hand. It completely consists of the following sections:
1. Environment, ahead of thought;
2. Fast bash;
3. Unix-way in working with files;
4. Vi (m), strict but fair.
