Abre una pestaña nueva y haz clic donde está el cursor.

Abre is the informal singular command form of abrir for tú.

• abrir = to open
• abres = you open
• abre = open! / open it!

So Abre una pestaña nueva means Open a new tab as an instruction.

This is very common in software instructions, tutorials, and spoken directions.

Because haz is the tú command of hacer.

• hacer = to do / to make
• hace = he/she does, or formal usted command in some contexts depending on punctuation and usage
• haz = do! / make!

So:

• haz clic = click
• literally: make a click

This is one of the most useful irregular commands to memorize:

• hacer → haz

Yes. Hacer clic is the standard and very common expression.

In Spain, you may also hear:

• haz clic
• pincha
• sometimes pulsa, depending on context

But haz clic is neutral, standard, and widely understood.

A quick comparison:

• haz clic = click
• pincha = click / click on, often heard in Spain
• pulsa = press, often more like pressing a button or key

So for a learner, haz clic is the safest expression to know.

Both are possible, but una pestaña nueva is the most natural choice in this technical context.

In Spanish, adjective position can change nuance:

• una pestaña nueva = a new tab, a tab that is newly opened/new
• una nueva pestaña = also a new tab, but sometimes sounds a little more like another tab or gives slightly more emphasis to new

In computer instructions, pestaña nueva is the standard collocation, much like new tab in English.

In everyday Spanish, pestaña usually means eyelash. But in computing, it means tab.

So:

• una pestaña nueva = a new tab

This is a very common tech word in Spanish.

Related words:

• ventana = window
• pestaña = tab

So a learner should be careful not to confuse tab and window.

Because Spanish normally omits subject pronouns when they are clear from the verb form.

Here, the command forms abre and haz already show that the instruction is for tú.

So Spanish naturally says:

• Abre una pestaña nueva y haz clic...

rather than:

• Tú abre una pestaña nueva y tú haz clic...

Including tú would usually sound unnecessary unless you want special emphasis.

Yes, this sentence is informal singular, addressed to tú.

Informal:

• Abre una pestaña nueva y haz clic donde está el cursor.

Formal singular (usted):

• Abra una pestaña nueva y haga clic donde está el cursor.

Plural in Spain (vosotros):

• Abrid una pestaña nueva y haced clic donde está el cursor.

So if you are reading instructions aimed at the general public, Spanish may use either the informal or formal style depending on tone.

Because here it is not a direct or indirect question. It is a relative word, meaning where in the sense of the place where.

• Haz clic donde está el cursor. = Click where the cursor is.

Use dónde with an accent in questions:

• ¿Dónde está el cursor? = Where is the cursor?

Use donde without an accent in statements like this one:

• Haz clic donde está el cursor.

This is a very common spelling point for learners.

Because estar is used for location.

The cursor is located somewhere on the screen, so Spanish says:

• el cursor está aquí = the cursor is here

Not:

• el cursor es aquí

A simple rule:

• ser = identity, what something is
• estar = location, state, position

Since the sentence refers to where the cursor is positioned, está is the correct verb.

Yes, cursor in Spanish is basically cursor in English.

In computer contexts, it can refer to:

• the mouse pointer
• the insertion point
• the on-screen marker showing position

In this sentence, it most likely means the pointer/indicator you should click at or near.

So el cursor is a straightforward vocabulary item and easy to remember because it looks almost the same as English.

Spanish uses the definite article very often where English may or may not use one.

Here, el cursor means the cursor, referring to the specific cursor visible on the screen.

So:

• donde está el cursor = where the cursor is

Using el sounds natural because both speaker and listener know which cursor is meant.

In standard Spanish, the most natural expression is still hacer clic.

You may occasionally hear forms like:

• clicar
• cliquear / clickear

but these are more colloquial, less standard, or vary by region.

For a learner, the safest option is:

• haz clic
• hacer clic

That will sound correct everywhere.

The negative tú commands are different from the positive ones.

Positive:

• abre
• haz clic

Negative:

• no abras
• no hagas clic

So:

• No abras una pestaña nueva.
• No hagas clic donde está el cursor.

This is useful because hacer changes again in the negative command:

• haz → no hagas

Yes. The h in Spanish is silent, so haz is pronounced roughly like az.

But the conjunction stays y, not something else:

• abre una pestaña nueva y haz clic

This is completely normal. The silent h does not affect the spelling of y here.

So just pronounce it smoothly:

• ... y haz clic ...

with the h silent.
