Si la página no responde, mueve el cursor, pulsa otra tecla y cierra la pestaña.

Because si without an accent means if.

• si = if
• sí = yes

So Si la página no responde... means If the page doesn’t respond...

This is a very common distinction in Spanish.

Responde is the present indicative form of responder for él/ella/usted.

In Spanish, the present tense often covers both:

• does not respond
• is not responding

So:

• la página no responde = the page doesn’t respond / isn’t responding

Spanish often uses the simple present where English might prefer a progressive form.

In Spanish, every noun has a grammatical gender, and página is feminine.

So you get:

• la página
• una página

This gender is grammatical, not necessarily logical. You usually just have to learn the noun together with its article.

Yes. They are informal singular commands addressed to tú.

They come from:

• mover → mueve
• pulsar → pulsa
• cerrar → cierra

So the sentence is giving instructions directly to one person:

• mueve el cursor
• pulsa otra tecla
• cierra la pestaña

This is very common in instructions, especially when the text speaks directly to the user.

Because Spanish usually leaves out subject pronouns when they are not needed.

The verb form already shows who the command is aimed at, so:

• mueve
• pulsa
• cierra

already imply you.

Including tú would usually only happen for emphasis or contrast.

Yes, it sounds very natural for Spain.

A big clue is pulsa. In Spain, pulsar is very common in technical instructions meaning press.

In Latin America, you might more often see:

• presiona
• oprime

So in Spain:

• pulsa otra tecla = press another key

Because otro / otra normally goes directly before the noun without an article.

So:

• otra tecla = another key
• not una otra tecla

This works like:

• otro día = another day
• otra vez = another time / again

Here pulsa means press in the sense of pressing a key or button.

So:

• pulsa otra tecla = press another key

In Spain, this is a standard verb in computer or device instructions. It is more specific and technical than some everyday alternatives.

In computing, pestaña means tab, as in a browser tab.

So:

• cierra la pestaña = close the tab

Outside computing, pestaña also means eyelash, so the word has more than one meaning. In tech contexts, though, tab is the intended meaning.

Spanish often does not need an explicit word like then in this kind of structure.

So:

• Si la página no responde, mueve el cursor... naturally means
• If the page doesn’t respond, move the cursor...

You could sometimes add words for emphasis in other contexts, but here Spanish normally just uses the conditional clause followed by the instructions.

This is standard Spanish punctuation for a list of actions.

The structure is:

• mueve el cursor, pulsa otra tecla y cierra la pestaña

This is like English:

• move the cursor, press another key, and close the tab

Spanish normally does not use the Oxford comma, so there is no comma before y here.

Yes. This sentence uses tú commands, which are informal singular. If you wanted a formal usted version, the commands would change:

• mueva el cursor
• pulse otra tecla
• cierre la pestaña

So the full formal version would be:

Si la página no responde, mueva el cursor, pulse otra tecla y cierre la pestaña.

Yes. Spanish, like English, often uses responder for devices, programs, pages, or systems.

So:

• la página no responde means the page is not reacting, not loading properly, or is frozen.

It is a very natural technical use of responder.

Yes, that is the most likely meaning.

In computer Spanish, cursor can refer to the on-screen pointer or indicator. In this context, mueve el cursor most naturally means move the cursor / mouse pointer to see whether the page is still reacting.

So this sentence is describing basic troubleshooting steps:

1. move the cursor
2. press another key
3. close the tab
