In addition to very important basic functions such as creating a multi-page document and saving in cmyk in vector programs, I would like to learn: How to repeat the last action in Inkscape?

Such a very useful function in Adobe illustrator is called transform again (ctr + d).

Example: https://youtu.be/o_9F72A_3fo

In Corel Draw it is called repeat command (ctrl + R).

How do you use a similar function in Inkscape???

Not available in Inkscape.

Hi! If anyone is still interested: a very similar function is Create Tiled Clones in Edit>Clone>Create Tiled Clones. It does a very similar job. I had the same problem as you but CTC solved my problems. Hope this helps.

I'm also searching for this option. Any updates on this? 

Yes, with 1.3 this option is already available. https://youtu.be/s4k0sBZN1rM?feature=shared&t=400

@mrks9, the feature in that video (ctrl + T and ctrl + D) is cool, nevertheless, it does not do the same function that ctrl + R does in Corel which is "repeating" the previous style (i.e, color, line weight/thickness, font size, etc...) that was just previously used. Thanks anyway.

Ah, okay, I misunderstood the question. My excuses.
