Hearts of Iron IV – Useful Hotkeys for Hearts of Iron 4

Introduction

I’ve decided to make a guide on hotkeys because I often see people who don’t use them at all, even in multiplayer, where speed of your micro managing is very important. And I will show some other hotkeys that not many people know about, even though they are useful.

Infantry management

• 
  S – Split selected divisions
  In my opinion, one of the most useful features in infantry management is ‘split’. It lets you quickly assign orders to a group of divisions, and using a hotkey for this saves you a lot of time.
  
• 
  Shift+K – Exercise until trained
  It’s one of those features that not many people know about. It lets you exercise divisions which experience level is lower than 3, without exercising and spending equipment of divisions that are already at third experience level.
  as you can see, only untrained divisions are attritioning
• 
  Ctrl+B – Toggle Strategic Redeployment
  Makes selected divisions railroad to their destination point. Works even if they are already on their way.
  
• Ctrl+1-9 to assign, 1-9 to select – Creates a shortcut for selected divisions
  Another unknown to many players hotkey. It lets you quickly select assigned divisions or jump to their location (if you click two times). I use it for tanks or other strong divisions.
  
• Ctrl+Right click on an attack bubble – Support Attack
  Divisions that are supporting an attack dont move away from their position after they managed to make the enemy retreat. Especially useful when divisions are defending from the other sides and you don’t want them to leave their tile after the attack is over.
  
• Shift + Right click – Creates a waypoint for selected divisions
  A very convenient and commonly used feature that allows you to navigate a path for your divisions.

Battleplan

Quick army management is important as well. It’s easy to find shortcuts for battleplan management so I will show only the most important ones.

• Z – Create a front line
• Ctrl+Left Click – Assign divisions to a front line
• X – Create an offensive line
• Alt – Edit Mode
  This one is useful to edit your offensive lines without losing battleplan bonus after your army almost reached the end of it

Map controls

• Backspace – Return to capital
  Useful when you hear a naval invasion sound and you have to quickly return to your country to defend from the invasion
  
• Ctrl + 1-9 – Creates a shortcut for a province
  Select a province and then press Ctrl + number. Lets you quickly move between the fronts.
  

Other stuff

• Ctrl+F9 – Toggles the Interface on/off for screenshots
  
• Ctrl + F10 – Creates a political map of current session
  This one is cool, I never knew about it before doing my little research on HOI4 shortcuts. Screenshots are found in game’s folder
  

Bonus

Decided to share a tip about navy, because why not.

There is an easy way to merge all your fleets into one. Useful for Japan and the UK.

Select a fleet and then Shift+Right click on other fleets

Assign selected fleets to a reserve fleet

Then press ‘G’

That’s it
