Sayfayı dikkatle kaydırsaydın, onay kutusunu hemen görebilirdin.

It is a past counterfactual conditional sentence: it talks about something that did not happen, and its possible result.

Pattern here:

• Sayfayı dikkatle kaydırsaydın = if you had scrolled the page carefully
• onay kutusunu hemen görebilirdin = you could have seen the checkbox right away

So the speaker is implying that the person didn’t scroll carefully, and therefore didn’t see the checkbox.

Kaydırsaydın means if you had scrolled.

It can be broken down like this:

• kaydır- = to slide / scroll
• -sa / -se = conditional if
• -ydı = past marker in this structure
• -n = you singular

So:

• kaydırsa = if you scroll / if you were to scroll
• kaydırsaydın = if you had scrolled

This is a very common Turkish way to make unreal past if-clauses.

In Turkish, kaydırmak literally means something like to slide / move by sliding, and in modern everyday language it is also used for scrolling or swiping on a screen.

So in a digital context:

• sayfayı kaydırmak = to scroll the page
• ekranı kaydırmak = to scroll/swipe the screen

Even if the original physical meaning is make something slide, this usage is very normal in tech-related Turkish.

Because sayfa is the direct object of the verb, and it is definite/specific.

• sayfa = page
• sayfayı = the page

Turkish often marks a specific direct object with the accusative ending:

• sayfa
  • -yı → sayfayı

The -y- is a buffer consonant, added because the noun ends in a vowel.

Here the speaker means a particular page, so sayfayı is the natural choice.

Dikkatle means carefully / with attention and works adverbially, so it modifies the verb kaydırmak.

• dikkat = attention
• dikkatle = with attention, carefully

By contrast, dikkatli is mainly an adjective meaning careful:

• dikkatli biri = a careful person

So here:

• dikkatle kaydırmak = to scroll carefully

You may also hear:

• dikkatlice kaydırmak
• dikkatli bir şekilde kaydırmak

All are possible, but dikkatle is short and natural.

Onay kutusu means checkbox.

Literally:

• onay = approval / confirmation
• kutu = box
• onay kutusu = checkbox

Then it becomes onay kutusunu because it is the definite direct object of the verb görmek:

• onay kutusu = the checkbox
• onay kutusunu = the checkbox (as object)

So in the sentence, it is the thing that the person could have seen.

This is a very common learner question.

Onay kutusu is a Turkish noun compound. In this type of compound, the second noun usually gets a 3rd person possessive ending:

• kutu = box
• onay kutusu = checkbox

That -su is part of the compound form.

Then, because the whole compound is a definite direct object, it also takes the accusative:

• onay kutusu
  • -nu → onay kutusunu

The -n- is a buffer consonant between the possessive ending and the case ending.

So:

• kutu-su = its box / box of approval → fixed compound meaning checkbox
• kutu-su-nu = the checkbox (object form)

Görebilirdin means you could have seen in this sentence.

Breakdown:

• gör- = see
• -ebil- = be able to / can
• -ir = aorist marker
• -di = past
• -n = you singular

So literally it is something like:

• you were able to see
• but in this conditional context, the natural English meaning is you could have seen

This is a very common form in Turkish for expressing possibility/ability in a hypothetical result clause.

Because the sentence is expressing a possible result, not a simple completed action.

• gördün = you saw
• görürdün = you would see / used to see
• görebilirdin = you could see / could have seen

Here the speaker is not saying the person definitely would have seen it in a plain factual sense; the sentence presents it as an achievable result:

• If you had scrolled carefully, you could have seen it right away

So -ebil- adds the idea of possibility/ability.

Hemen means immediately, right away, or at once.

So:

• onay kutusunu hemen görebilirdin = you could have seen the checkbox right away

It emphasizes that the checkbox was not hard to find; the speaker suggests that with careful scrolling, it would have appeared quickly.

It is addressed to one person informally, because of the ending -n in both verbs:

• kaydırsaydın
• görebilirdin

This is 2nd person singular informal: you = sen

If you wanted the polite/plural form (siz), you would say:

• Sayfayı dikkatle kaydırsaydınız, onay kutusunu hemen görebilirdiniz.

Yes to both.

Turkish word order is flexible, although the verb usually stays near the end of its clause.

You can add eğer = if:

• Eğer sayfayı dikkatle kaydırsaydın, onay kutusunu hemen görebilirdin.

You can also reverse the clauses:

• Onay kutusunu hemen görebilirdin, sayfayı dikkatle kaydırsaydın.

But the original order is very natural because Turkish often puts the condition first.

That would change the time and the feeling of the sentence.

• kaydırsan = if you scroll / if you were to scroll
• kaydırsaydın = if you had scrolled

So:

• Sayfayı dikkatle kaydırsan, onay kutusunu hemen görebilirsin.
  = If you scroll the page carefully, you can see the checkbox right away.

This sounds like advice about the present or future.

But the original:

• Sayfayı dikkatle kaydırsaydın, onay kutusunu hemen görebilirdin.

is about a past situation that did not happen. It has a mild you should have done that feeling.

Yes, a little.

Grammatically it is just a conditional sentence, but pragmatically it often sounds like:

• You would have seen it if you had scrolled carefully
• in other words: you missed it because you weren’t careful

So depending on tone, it can sound:

• neutral and explanatory
• mildly reproachful
• slightly defensive, especially in tech support or online discussions

The grammar itself does not force criticism, but this kind of counterfactual often carries that implication.
