LibreOffice Start page.
This doesn't exist in Microsoft office. From here you can:
- Launch any of the 6 Office programs (create a new document)
- Open a recent file, from the grid of recent files.
- Open any file on your computer, from the Open File button
- Edit your templates
- Access Help and the Extensions webpage.

LibreOffice Writer.
LibreOffice Writer is the equivalent of MS Word. It has all of the basic functions, like Font, Text size, Alignment, and drawing functions, like Rectangles, Circles and various shapes, like Stars, Call outs (Speech Bubbles) and Arrows.
It can be launched with the command libreoffice --writer
(creates a new document), searching the dash for "Writer", or clicking its icon on the launcher.
Here is the icon, and a cropped screenshot of the Writer window:

As you can see, in the top bar is the standard tool bars, File
, Edit
etc. and the formatting tool bar - Font + Size, Colour etc.
In the bottom, there is the Shapes toolbar with the Arrows etc.
LibreOffice Calc.
LibreOffice Calc is the equivalent of MS Excel. It has all of the basic functions, like Font, Text size, Alignment, and some more advanced ones, like Formula insertion, Charts, Cell Colouring and Conditional Formatting.
It can be launched with the command libreoffice --calc
(creates a new document), searching the dash for "Calc" (often Calculator is the first result), or clicking its icon on the launcher.
Here is the icon, and a cropped screenshot of the Calc window:

As you can see, in the top bar is the standard tool bars, File, Edit, etc., and the formatting toolbar - Font + Size, Colour etc.
At the bottom is the Find search bar. This can be focused with the standard Ctrl+F shortcut.
LibreOffice Impress.
Libre Office Impress is the equivalent of MS Power Point. It has all of the basic functions, like Font, Text size, Alignment, and others exclusive to Impress, like Custom Animation, different Slide views and default text boxes for tiles that come with the templates.

(Creates a new document), searching the dash for "Impress", or clicking its icon on the launcher.
Here is the icon, and a cropped screenshot of the Draw window:

At the bottom is the Shapes tool bar. It has all the shapes that Writer has, but also some extras, like certain freehand shapes, more like Draw (below).
Along the side are the tools exclusive to Impress, like Custom Animation, Master Slides and Slide Transitions.
LibreOffice Draw.
LibreOffice Draw is the equivalent of MS Publisher, a program that doesn't come in the basic MS Office package. It has all of the basic functions, like Font, Text size, Alignment, and others exclusive to Draw, like freehand drawing and better shape manipulation.
It can be launched with the command libreoffice --draw
(creates a new document), searching the dash for "Draw", or clicking its icon on the launcher.
Here is the icon, and a cropped screenshot of the Draw window:

At the bottom is the Shapes tool bar. It has all the shapes that Writer has, but also some extras, like certain freehand shapes.
LibreOffice Math.
LibreOffice Math has no equivalent to an MS product. It is very different to all the others, it hasn't got the font tools.
It can be launched with the command libreoffice --math
(creates a new document), searching the dash for "Math, or clicking its icon on the launcher.
Here is the icon, and a cropped screenshot of the Math window.

As you can see, in the top bar is the standard tool bars, File, Edit, etc., but in the standard bar there are unique tools like zoom and special Greek symbols.
At the bottom is not a toolbar, that is where you enter the formula. The point of Math is to present your formula in a professional way, instead of trying to get /
and +
aligned, and formulas over each other.
As an example it converts this:
{π} over { 2 } = sum from { { i = 0 } } to { infinity } { k!} over { (2k +1)!! }
to this:

LibreOffice Base.
LibreOffice Base is the equivalent of MS Access. It is a very specialised tool, and is designed completely around creating databases.
It can be launched with the command libreoffice --base
(Creates a new document), searching the dash for "Base", or clicking its icon on the launcher.
Here is the icon, and a cropped screenshot of the Base window:

As you can see, in the top bar is the standard tool bars, File, Edit, etc., however in this view most features are disabled, as this is the navigation window, with links to the base wizard.
In the bottom, there is a status bar with details about what you are working on (not included in the screenshot).
Keyboard shortcuts.
Ctrl+C - Copy
Ctrl+X - Cut
Ctrl+V - Paste
Ctrl+Z - Undo
Ctrl+Y / Ctrl+Shift+Z - Redo
Ctrl+P - Print
Ctrl+A - Select All
F7 - Spell Check (Check spelling as you type is an option, which I think is enabled by default.)
Ctrl+S - Save
Ctrl+Shift+S - Save as
A list of general keyboard short cuts. Here are the specific ones for Writer and Calc.
Compatibility
Compatibility with other document types is fairly good. MS Office is not as good at decoding .odt
documents, but LibreOffice is quite good at saving in that format. Some features (especially formatting of tables, for me) are a bit hit and miss. If compatibility is key, I suggest using the built in export feature to export it to a .pdf
. Normally however, just saving as a .doc
or .docx
is enough for windows users to access it.
They do use different methods to create the same thing, which is why you get issues.
Most of this came from my memory and experiences. The wiki is:
- Less biased.
- More reputable.
- Has more info, and the info is more accurate.
So I would suggest you have a look in it for information I have (accidentally or purposefully) left out.
So, essentially, no, there is no alternative to OneNote built-in; you need to look outside of LibreOffice for this.
