Se clicares no ícone azul, podes abrir o índice digital no computador.

Here se means if. It introduces a condition:

Se clicares no ícone azul, ... = If you click the blue icon, ...

In Portuguese, se can also have other uses, but in this sentence it is simply a conditional word.

Because after se when talking about a possible future action, Portuguese normally uses the future subjunctive.

So:

• Se clicares... = If you click...
• clicares is the future subjunctive form of clicar for tu

Using Se clicas... would not be the normal standard choice for this meaning. Se clicas... can sound more like a habitual situation in some contexts, not a one-time future instruction.

Yes. Both verb forms point to tu:

• clicares = future subjunctive, tu
• podes = present indicative, tu

Portuguese often drops subject pronouns when the verb ending already makes the person clear. So the full version could be:

Se tu clicares no ícone azul, tu podes abrir o índice digital no computador.

But in natural Portuguese, the pronouns are usually omitted.

Because after the modal verb poder (can / to be able to), the next verb stays in the infinitive.

So:

• podes abrir = you can open
• not podes abres

This works like English:

• you can open
• not you can opens

In Portuguese, the present tense is often used for a future result, especially in everyday speech and instructions.

So:

• podes abrir = you can open / you’ll be able to open
• poderás abrir is also possible, but it sounds more explicitly future and often a bit more formal

In an instruction-like sentence, podes abrir sounds very natural.

No is a contraction of em + o.

• em + o = no

So:

• clicar no ícone = click on the icon
• no computador = on/in the computer

With clicar, Portuguese commonly uses em:

• clicar em algo = to click on something

That is why you get no ícone.

Because adjectives often come after the noun in Portuguese.

So the normal order is:

• ícone azul = blue icon

This is the most neutral, standard order. Putting the adjective before the noun is much less common here and can sound marked or stylistic.

Here índice most likely means index or table of contents, especially in a digital or document context.

So índice digital could mean something like:

• a digital index
• a digital table of contents
• a navigational contents section in a file or platform

It does not mean a mathematical index here.

Yes. Clicar is very common in computer and internet language in Portugal.

A few related points:

• clicar = to click
• it is widely used in everyday speech and instructions
• in more formal or technical wording, you may also see verbs like selecionar, premir, or carregar, depending on the exact action

But clicar is completely normal and natural.

You would normally switch to the 3rd person singular forms:

Se clicar no ícone azul, pode abrir o índice digital no computador.

That is the usual formal pattern in Portuguese from Portugal.

A few notes:

• In Portugal, people often avoid saying você directly.
• So Se clicar..., pode... is usually more natural than Se você clicar..., você pode...
• Both are grammatical, but the version without você sounds more idiomatic in many contexts.

Yes, the comma is standard and natural when the if-clause comes first:

Se clicares no ícone azul, podes abrir o índice digital no computador.

If you put the main clause first, you would normally write:

Podes abrir o índice digital no computador se clicares no ícone azul.

In that order, a comma is often not needed.

Yes. Portuguese allows both orders:

• Se clicares no ícone azul, podes abrir o índice digital no computador.
• Podes abrir o índice digital no computador se clicares no ícone azul.

Both mean the same thing. The first version is slightly more instruction-like because it presents the condition first.

A useful rough guide is:

Se cli-CA-res no Í-co-ne a-ZUL, PO-des a-BRIR o ÍN-di-ce di-gi-TAL no com-pu-ta-DOR.

Main stress:

• clicares → cliCAres
• ícone → Ícone
• azul → aZUL
• podes → POdes
• abrir → aBRIR
• índice → ÍNdice
• digital → digiTAL
• computador → computaDOR

In European Portuguese, unstressed vowels are often reduced, so the real pronunciation is usually less open and clearer in rhythm than this spelling-based guide suggests.
