Essential keyboard shortcuts

Seriously, who needs a mouse when editing text? — Robert Vanden Eynde

The mouse, that's slow... But trackpad? That's wooorse! — Robert Vanden Eynde

Here is a list of the most useful keyboard shortcuts to edit text, those work even on Facebook, you don't have to read them but it's useful to write code very fast trust me!

The keys

Do you know the use of all your keyboard keys?

Symbol	Use
`←↓↑→`	Arrows keys (touches directionnelles) move the cursor.
`⇧Shift`	`⇧Shift` (Maj. on keyboard from France) allows writing a level 2 character, like the upper case letters, the dot on a french Azerty keyboard or the parenthesis on a US-Qwerty.
`AltGr`	`AltGr` (Right Alt) allows writing level 3 characters like the `€` on a french Azerty, the key is pressed using the right thumb (`⌥ Option` on Mac). Let's notice that some keyboards don't have a `AltGr` key, one must press `Ctrl`+`Alt`.
`⌫ Backspace`	Backspace (`Ret. Arr.` for Retour Arrière on keyboard from France) deletes the character to the left.
`Delete ⌦`	`Delete ⌦` (`Suppr.` on keyboard from France) deletes the character to the right (sometimes `⌃Control`+`D`, sometimes `Fn`+`⌫` on Mac).
`↵ Enter`	`↵ Enter` (Entrée on keyboards from France, `Return` on US keyboards) inserts a new line or executes a command like send a message.
`⎋ Escape`	Very useful in certain applications but is generally part of a functionality that must be guessed, `⎋ Escape` (Échap. for (s')Échapper on keyboards from France) goes back to default state, it depends a lot on the applications but this key is often used to go back to the normal state of a programm, like for example when you open a settings menu or a search menu and you want to quickly close it.
`Pause`	This key is useless... So I use it as a `⎄ Compose` Key natively on Linux or with WinCompose on Windows.

The classics

The classics, let's notice that Ctrl is pressed using the ⑤ little finger of the left hand or on Mac ⌘ Command is pressed using the ① thumb of the left hand.

When I was 10 years old, I learned Ctrl+C, Ctrl+V on the keyboard only, it's like 5 years later I learned that one could do it via right click...

`Ctrl` + `Z`	Undo, using left ⑤ little finger finger for `Ctrl` (`⌘` + `Z` on Mac using the left ① thumb for `⌘`).
`Ctrl` + `C`	Copy, using left ⑤ little finger finger for `Ctrl` (`⌘` + `C` on Mac using the left ① thumb for `⌘`).
`Ctrl` + `V`	Paste, using left ⑤ little finger finger for `Ctrl` (`⌘` + `V` on Mac using the left ① thumb for `⌘`).
`Ctrl` + `X`	Cut, using left ⑤ little finger finger for `Ctrl` (`⌘` + `X` on Mac using the left ① thumb for `⌘`).
`Ctrl`+`⇧Shift`+`Z`	Redo, it's `Ctrl` + `Z` inverse operation, using our left ④ ring finger for `⇧Shift` or on Mac we will rather use the left ⑤ little finger for `⇧Shift` because the ① thumb is used for `⌘` (`⌘` + `⇧` + `Z` on Mac). Note: In the majority of my shortcuts, `Ctrl`+`⇧Shift`+Stuff is the inverse of `Ctrl`+Stuff except when the inverse operation is not useful because `Ctrl`+Z (Undo) does its job very well.
`Ctrl` + `Y`	Redo (`Ctrl` + `Z` inverse operation) in some applications that are not based on Linux (`⌘` + `Y` on Mac).
`Ctrl` + `F`	Search! (Ctrl Find) (`⌘` + `F` on Mac).
`⇱ Home`	Go to the beginning of the line or the page, can also be used with `⇧Shift` to select some text.
`⇲ End`	Go to the end of the line or the page, can also be used with `⇧Shift` to select some text.

Select, delete and move

And now, the infamous ones!

`Ctrl`+`→`	Next word (`⌥`+`→` on Mac). `Ctrl` (left ⑤ little finger) + `→` (right hand) if the Left `Ctrl` is used or `Ctrl` (right ① thumb) + `→` (right ⑤ little finger) to use only one hand.
`Ctrl`+`←`	Previous word (`⌥`+`←` on Mac). `Ctrl` (left ⑤ little finger) + `→` (right hand) if the Left `Ctrl` is used or `Ctrl` (right ① thumb) + `←` (right ② index finger) to use only one hand.
`⇧Shift`+`→`	Select a character to the right. `⇧Shift` (right ② index finger) + `→` (right ⑤ little finger) to use only one hand.
`⇧Shift`+`←`	Select a character to the left. `⇧Shift` (right ② index finger) + `←` (right ③ middle finger) to use only one hand if the `⇧Shift` is to the left of the arrow keys.
`Ctrl`+`⇧Shift`+`→`	Select a word to the right (`⌥`+`⇧`+`→` on Mac). Possible to do with the right hand only and a some habits.
`Ctrl`+`⇧Shift`+`←`	Select a word to the left (`⌥`+`⇧`+`←` on Mac). Possible to do with the right hand only and a some habits.
`Ctrl`+`⌫`	Delete previous word (`⌥`+`⌫` on Mac), it's very handy to delete multiple words, you just have to hold `Ctrl` then press `⌫ Backspace` multiple times.
`Ctrl`+`Delete ⌦`	Delete next word (`⌥`+`⌫` on Mac), same note as previous line.
Double click	Select the word under the mouse.
Triple click	Select the line under the mouse, or sometimes the whole paragraph.
`⇧Shift`+`⇱ Home`	Select until the beginning of the line.
`⇧Shift`+`⇲ End`	Select until the end of the line.
`⇧Shift`+Click	Select from the cursor position until the position of the click.

It works everywhere even on Facebook! And let's notice that there is a Ctrl and Shift key next to the arrow keys so all of these shortcuts can be done with the right hand only!

Codes have lines

Moreover, here are some useful shortcuts when you edit code: :

`Ctrl`+`D`	Delete a line (`⌘`+`D` on Mac).
`Ctrl`+`⇧Shift`+`D`	Duplicate a line (`⌘`+`⇧`+`D` on Mac). Sometimes `Alt`+`⇧Shift`+`↓`
`Ctrl`+`⇧Shift`+`↑/↓`	Move one or more lines up/down (`⌘` + `⇧` + `↑/↓` on Mac). Useful in order to move one or multiple lignes that were duplicated (the fingers are still on `Ctrl`+`⇧Shift`). Sometimes `Alt`+`↓`.
`Tab ↹`	Indent the selected lines. Sometimes `Ctrl`+`I`.
`⇧Shift`+`Tab ↹`	Dedent the selected lines. Sometimes `Ctrl`+`⇧Shift`+`I`.
`Ctrl`+`G`	Goto line number n (`⌘`+`G` on Mac). Sometimes `Ctrl`+`L` (Ctrl Line).

It also works when you have multiple selected lines, this delete line shortcuts looks very silly but you have no idea how powerful it is...

Web browser, Firefox, Chrome and others

We spend too much time in our web browser to be inefficient (I ♥ tabs):

`Ctrl` + `T`	New tab (then I write my search) (`⌘` + `T` on Mac).
`Ctrl` + `L`	Select location bar (`⌘` + `L` on Mac). `Alt`+`D` also works but I think using only `Ctrl`+`Key` or `Ctrl`+`Shift`+`Key` is more effective.
`Ctrl` + `W`	Close tab (sometimes, it happens) (`⌘` + `W` on Mac).
`Ctrl`+`⇧Shift`+`T`	Restore last closed tab (`⌘`+`⇧`+`T` on Mac).
`Ctrl` + `F`	Search! (Ctrl Find) (`⌘` + `F` on Mac).
Middle click	On a link, open it in a new tab.
`Ctrl`+Click	On a link, open it in a new tab.
Middle click	On a tab, close it.

Mais encore...

Je pourrais encore parler...

de l'art de l'Alt-Tabbing moderne (Alt+Tab va dans la dernière fenêtre ouverte !),
du Control-Tabbing et du setting Firefox pour l'Alt-Tabbing,
de la barre en haut de Firefox (et Chrome) s'activant avec Ctrl+T ou Ctrl+L qui sert :
- à rechercher avec le navigateur de son choix comme duckduckgo.com
- mais aussi facilement aller dans un onglet ouvert
- ou rechercher via un site spécifique en tappant par exemple yt Acapella Science Shape of You pour aller sur cette recherche youtube ou encore fren banane pour aller sur wordreference.com/fren/banane,
de l'Alt+PageUp en main libre,
du Chercher-Remplacer en mode Texte, Échappement ou Regex,
du copier coller sans les mains (le copier coller via le clic milieu) qui existe depuis toujours sur Linux et qui n'a étonnament toujours pas été copié sur Windows,
du copier coller du fainénant (oh, c'est aussi le copier coller clic milieu)
du copier coller du mec qui n'a qu'une main sur la souris (toujours notre ami)
de la stupidité de la touche NumLock et CapsLock sous Windows,
du déplacement furtif de fenêtres via ⊞ Windows+←↓↑→,
de ⊞ Windows+D pour aller au bureau... mais que le bureau ça ne sert à rien,
du fait que pour lancer un programme on fait juste ⊞ Windows suivi des premières lettres du programme suivi de ↵ Enter,
que la touche ⌘ Command sous Mac avait avant le logo d'une pomme et donc on parle de Pomme C, Pomme V,
de KDE qui est génial sous linux,
de KDE qui est génial sous windows,
de KDE Plasma qui a la fonctionnalité de faire des tab dans les fenêtres mais ils l'ont enlevée car c'était inutile et maintenant windows dit qu'il veut faire ça mais que « c difficil kan mêm »,
de linux qui est toujours en avance mais vu qu'il y des milliers de créateurs c'est parfois un peu funky,
d'informatique et d'éducation pendant des heures...
